Why Do Cats Purr? What Your Cat’s Purring Really Means

Few sounds are as soothing as a cat curled up on your lap, rumbling away. But why do cats purr? Most people assume it simply means “I’m happy” – and often it does. Yet cats also purr when they are frightened, hungry, injured, giving birth and even dying. Purring is one of the most versatile forms of communication in the animal kingdom, and scientists are still working out everything it does.

In this article we look at how purring actually works, the seven main reasons cats purr, the fascinating evidence that purring may help cats heal, and how to tell a happy purr from a worried one.

How Do Cats Purr?

For a long time nobody knew. The leading explanation today is that purring is produced by the laryngeal (voice box) muscles, which twitch rapidly – around 25 to 150 times per second – under the control of a neural oscillator in the brain. As the cat breathes in and out, air passing over the twitching vocal folds produces the continuous rumble. That is why, unlike a meow, a purr continues on both the in-breath and the out-breath.

Research published in 2023 added a twist: cat vocal folds contain unusual pads of connective tissue that may allow them to produce low-frequency purring passively, without constant muscle input – similar to how humans produce “vocal fry”. The truth is probably a combination of both mechanisms.

Domestic cats purr at a frequency of roughly 25 to 50 Hz, with harmonics extending higher – a range that, as we’ll see, may be biologically significant.

7 Reasons Why Cats Purr

1. Contentment

The purr we all recognise. A relaxed cat on a warm lap, being stroked in its favourite spot, purrs to express pleasure and to communicate “keep doing that”. This purr is accompanied by relaxed body language: half-closed eyes, a loose body, slow blinks, and often kneading with the front paws.

2. Communication between mother and kittens

Kittens begin purring when they are just two or three days old – while they are still blind and deaf. Purring while nursing tells the mother “I’m here and I’m fine”, and the vibration helps her locate them. The mother purrs back to reassure and soothe her litter. Purring is, in fact, one of the first ways a cat ever communicates.

3. Asking for something – the “solicitation purr”

Researchers at the University of Sussex discovered that cats produce a special purr when they want food or attention. This solicitation purr embeds a high-frequency cry (around 220–520 Hz, close to the frequency of a human baby’s cry) inside the ordinary low purr. Owners rate it as more urgent and harder to ignore than a normal purr – even people who have never owned a cat. In other words, your cat has learned to exploit your parental instincts.

4. Self-soothing when stressed or frightened

Cats frequently purr at the vet, during car journeys, or when a new pet arrives. This is not happiness. Much like a nervous person humming or a child sucking their thumb, purring appears to be a way cats calm themselves. Look at the rest of the body: flattened ears, dilated pupils, a tucked tail or a crouched posture mean this purr is about coping, not contentment. Our guide to the signs your cat is stressed covers the other clues.

5. Pain and injury

Cats with broken bones, after surgery or with serious illness often purr, sometimes constantly. Vets believe this is partly self-soothing and partly – as explained below – a genuine healing mechanism. A cat that purrs while hiding, refusing food or holding a limb awkwardly should be seen by a vet.

6. Healing and bone strengthening

Here is where purring becomes truly remarkable. The dominant purr frequencies of 25–50 Hz (and harmonics at 100 Hz and 150 Hz) are the same frequencies that studies in humans and animals have found to promote bone density, aid fracture healing, relieve pain and reduce swelling. Vibration therapy at these frequencies is used in human medicine. Researchers have proposed that purring is a low-energy way for cats to keep their bones and muscles strong during the long hours they spend resting – which may help explain why cats so often survive falls and injuries that would be devastating for a dog of the same size. The evidence is still circumstantial, but it is compelling.

7. During birth and at the end of life

Queens purr while giving birth, probably for pain relief and to calm themselves. Sadly, cats also often purr when they are very ill or dying – again most likely a self-soothing response rather than a sign of comfort.

Is Purring Good for Humans Too?

Quite possibly. Studies have linked cat ownership with lower blood pressure and a reduced risk of heart attack and stroke, and the calming effect of a purring cat is at least part of the reason. The 25–150 Hz range overlaps with frequencies used therapeutically for pain and wound healing in people, and simply stroking a purring cat measurably reduces stress hormones. The purr is, in a very real sense, therapy for both of you.

How to Tell What Your Cat’s Purr Means

The sound alone doesn’t tell you much – the context and body language do:

Body language	Likely meaning
Relaxed posture, slow blinks, kneading, tail loosely curled	Content and happy
Rubbing against you, staring, purr sounds urgent, near food bowl	Solicitation – wants food or attention
Flattened ears, wide pupils, crouched, tail tucked or thrashing	Stressed or frightened – self-soothing
Hiding, not eating, limping, purring for long periods alone	Possible pain or illness – see a vet
Kitten purring while feeding	Communicating with mother

Why Doesn’t My Cat Purr?

Some perfectly healthy cats rarely or never purr audibly. Feral cats and cats that were separated from their mothers very young purr less, possibly because they had less opportunity to learn the behaviour. Some cats purr so quietly you can only feel it by placing a hand on the chest or throat. A cat that used to purr and has suddenly stopped, however, may have a sore throat, respiratory infection or be unwell – worth a vet check.

Do Big Cats Purr?

Cats are broadly divided into two groups. Small cats – including the domestic cat, bobcat, lynx, cheetah, cougar and serval – can purr but cannot roar. Big cats of the genus Panthera – lions, tigers, leopards and jaguars – can roar but cannot produce a true purr, because of differences in the structure of the hyoid bone and larynx. Cheetahs are the largest cats that genuinely purr, and they do so loudly.

Frequently Asked Questions

Why do cats purr when you stroke them?

Stroking mimics the grooming a cat received from its mother, triggering the same contentment purr it produced as a kitten.

Why does my cat purr and then bite me?

This is “petting-induced overstimulation”. The purr was genuine, but the stroking went on too long or touched a sensitive spot. Watch for a twitching tail or skin rippling along the back, and stop before the bite.

Why do cats purr so loud?

Purr volume varies hugely between individuals. The Guinness record for the loudest purr is 67.8 decibels – about as loud as a dishwasher. Loud purring is not a sign of anything wrong.

Do cats purr when they sleep?

Yes, some cats purr softly while dozing, especially when curled up next to their owner or another cat.

Is purring a sign that a cat is in pain?

It can be. Purring in a cat that is also hiding, off its food, or reluctant to move should prompt a vet visit.

Final Thoughts

So why do cats purr? To say “I’m happy”, “feed me”, “I’m here”, “I’m scared” and possibly “I’m healing” – all with the same extraordinary sound. Learn to read the body language that goes with it and you’ll understand your cat far better. And the next time a purring cat settles on your lap, remember it may be doing your health as much good as its own. Curious how many years of purring you can look forward to?

Why Does My Dog Eat Grass? 7 Reasons and When to Worry

Why Does My Dog Eat Grass? 7 Reasons and When to Worry

You let your dog out into the garden and, instead of doing its business, it starts grazing like a sheep. Why does my dog eat grass? It’s one of the most common questions dog owners ask their vet – and the reassuring answer is that grass eating is normal, extremely common and, in most cases, nothing to worry about.

That said, there are a few situations where grass eating is a signal that something is wrong. This guide explains the seven real reasons dogs eat grass, what the science says about the “dogs eat grass to make themselves sick” theory, the genuine risks, and how to reduce the habit if it bothers you.

Is It Normal for Dogs to Eat Grass?

Yes. In a well-known survey by researchers at the University of California, Davis, 79% of dog owners reported that their dog ate grass or other plants regularly. Importantly, only 9% of those dogs seemed unwell before eating grass and only 22% vomited afterwards. In other words, the vast majority of grass eating has nothing to do with illness.

Vets consider grass eating a normal canine behaviour – technically a mild form of “pica” (eating non-food items) that is so widespread it barely deserves the label.

7 Reasons Why Dogs Eat Grass

1. It’s instinctive

Dogs are not true carnivores – they are opportunistic omnivores descended from wolves. Studies of wild wolves and coyotes find grass and other plant material in a large share of their droppings, and wolves also consume the stomach contents of their prey. Your dog’s ancestors ate plants; your dog is simply doing what comes naturally.

2. They like the taste and texture

Many dogs clearly seek out fresh, sweet spring grass and ignore dry summer grass. Dew-covered morning grass is a favourite. For some dogs it is quite simply a snack they enjoy.

3. They want more fibre

Grass is roughage. Some dogs on low-fibre diets appear to graze to help food move through the digestive system, and in a few documented cases switching to a higher-fibre diet stopped the behaviour entirely.

4. Boredom or anxiety

A dog left alone in the garden for hours with nothing to do will find its own entertainment – and grazing is an easy, self-soothing activity. Dogs that eat grass mainly when their owner is absent, or during stressful events, are often eating out of boredom or anxiety rather than hunger.

5. An upset stomach (sometimes)

The classic explanation is that dogs eat grass to make themselves vomit when they feel nauseous. The evidence is weaker than most people think – as noted above, fewer than a quarter of grass-eating dogs vomit afterwards. But some dogs do gulp grass frantically when nauseous, and the long, tickly blades may indeed trigger vomiting. If your dog eats grass quickly and urgently and then throws up, an upset stomach is a plausible cause.

6. Attention seeking

If every time your dog starts nibbling the lawn you rush over shouting “leave it!”, a clever dog quickly learns that grass eating gets a reaction. For attention-hungry dogs, even negative attention is a reward.

7. A nutritional deficiency (rare)

True nutritional deficiencies are uncommon in dogs fed a complete commercial diet, but dogs on unbalanced home-cooked or raw diets may seek out plants to compensate. If your dog eats large amounts of grass and other odd items like soil, ask your vet to review the diet.

Does Eating Grass Mean My Dog Is Sick?

Usually not. But grass eating combined with any of the following deserves a vet visit:

Vomiting more than once or twice a week
Diarrhoea, or blood in the vomit or stool
Lethargy, loss of appetite or weight loss
Frantic, compulsive grass eating that starts suddenly
Licking the lips, drooling or gulping – signs of nausea or acid reflux
Eating other non-food items (soil, stones, fabric)

Possible underlying causes include gastritis, acid reflux, inflammatory bowel disease, pancreatitis, intestinal parasites or, less commonly, liver disease. All of these are treatable, and none get better by being ignored.

Is Eating Grass Bad for Dogs? The Real Risks

The grass itself is harmless. The dangers are what may be on it or in it:

Pesticides, herbicides and fertilisers – lawn chemicals can cause poisoning. Keep dogs off treated lawns for at least as long as the product label states, and choose pet-safe products.
Parasites – grass contaminated by other animals’ faeces can carry roundworm and hookworm eggs. In the UK and Europe, slugs and snails on grass can transmit lungworm, which is potentially fatal – another good reason for regular worming.
Toxic plants – dogs that graze indiscriminately may also chew daffodil bulbs, foxgloves, lilies or other poisonous garden plants.
Sharp or coarse grass – ornamental grasses and grass seeds (awns) can lodge in the throat, paws or ears.
Vomiting – occasional vomiting after grazing is not dangerous in itself, but repeated vomiting can irritate the stomach.

How to Stop Your Dog Eating Grass

If your dog is healthy and eats grass occasionally, you don’t need to stop it. If you’d rather reduce the habit, or your dog is grazing where chemicals may have been used, try these:

Rule out a medical cause with a vet check, especially if the behaviour is new or intense.
Add fibre to the diet – a spoonful of plain cooked pumpkin or green beans, or a switch to a higher-fibre complete food, satisfies many grazers.
Increase exercise and mental stimulation – longer walks, scent games, puzzle feeders and training sessions cure boredom grazing.
Don’t leave the dog alone in the garden for long stretches.
Teach “leave it” and reward your dog for turning away from grass – and ignore the behaviour otherwise, so it stops working as an attention grab.
Offer a safe alternative – a tray of pesticide-free wheatgrass or “pet grass” grown indoors lets your dog graze safely.
Keep the lawn chemical-free and worm your dog regularly.

Frequently Asked Questions

Why does my dog eat grass and then throw up?

Some dogs gulp long grass when they feel nauseous, and the blades tickle the throat and stomach lining enough to trigger vomiting. If it happens occasionally your dog is probably fine; if it happens weekly, see your vet.

Why does my dog eat grass every morning?

Morning grass is fresh and covered in dew, which many dogs love. An empty stomach overnight can also cause mild nausea (bile reflux) – try a small bedtime snack and see if the morning grazing stops.

Why does my puppy eat grass?

Puppies explore the world with their mouths and eat all sorts of things. Grass is one of the safer options, but supervise to make sure they aren’t also eating stones, mulch or toxic plants.

Should I let my dog eat grass?

Yes, as long as the grass is free of chemicals and your dog is otherwise well. It is a normal behaviour that most dogs enjoy.

Final Thoughts

Why does my dog eat grass? Most likely because it’s a dog, it likes it, and its wolf ancestors did the same. Keep an eye out for the warning signs listed above, keep your lawn chemical-free, and otherwise let your dog enjoy its salad.

Can Dogs Eat Grapes? Why Grapes and Raisins Are Toxic to Dogs

Can Dogs Eat Grapes? Why Grapes and Raisins Are Toxic to Dogs

Can dogs eat grapes? No – and this is one of the few food questions where the answer is an absolute. Grapes, raisins, sultanas and currants are toxic to dogs and can cause sudden, sometimes fatal kidney failure. There is no known safe amount, the reaction is unpredictable, and a dog that shrugged off a grape last year may become seriously ill from one today.

This article explains why grapes are so dangerous, how many grapes are toxic to dogs, the symptoms of grape poisoning, exactly what to do if your dog ate grapes, and which fruits you can safely share instead.

Why Are Grapes Toxic to Dogs?

For decades vets knew grapes caused acute kidney injury in dogs without knowing why. In 2021, toxicologists at the ASPCA Animal Poison Control Center identified the likely culprit: tartaric acid (and its salt, potassium bitartrate), which occurs naturally in grapes in high and highly variable amounts. Dogs are unusually sensitive to it, and it damages the cells of the kidney tubules.

Because the amount of tartaric acid varies wildly between grape varieties, ripeness and growing conditions, one bunch may be relatively low-risk and another dangerously high. That is why there is no safe dose.

Everything made from grapes carries the same risk:

Fresh grapes – red, green, black, seeded or seedless
Raisins, sultanas and currants (dried grapes are more concentrated, so even more dangerous by weight)
Grape juice and grape jelly or jam
Foods containing raisins: fruit cake, mince pies, hot cross buns, trail mix, granola, oatmeal cookies, some cereals and bread

Wine is unlikely to be offered to a dog, but it is also grape-based and doubly dangerous because of the alcohol.

How Many Grapes Are Toxic to Dogs?

There is no established toxic dose. Cases of kidney failure have been reported after as few as 4 or 5 grapes in a 9 kg (20 lb) dog, and after a single small box of raisins. Other dogs have eaten a whole bunch with no apparent effect. Because you cannot predict which group your dog falls into, vets treat any grape or raisin ingestion as an emergency.

Smaller dogs and puppies are at greater risk simply because the dose per kilogram of body weight is higher. But large dogs are not immune – Labradors and Golden Retrievers, who eat first and think later, are frequently among the cases seen by poison control.

Symptoms of Grape Poisoning in Dogs

Signs usually appear within 6 to 12 hours of eating grapes, though vomiting can begin sooner. Watch for:

Vomiting – often the first sign; you may see grape or raisin pieces
Diarrhoea
Loss of appetite
Lethargy, weakness or unusual quietness
Abdominal pain – hunched posture, reluctance to be touched
Dehydration – dry gums, panting, sunken eyes
Increased thirst and urination at first…
…then decreased or no urination (24 to 72 hours later) – the hallmark of kidney failure
Bad breath with an ammonia smell, tremors or seizures in advanced cases

Once a dog stops producing urine, the outlook is poor. This is why early treatment – before symptoms appear – makes such a difference.

What to Do If Your Dog Ate Grapes

1. Act immediately – don’t wait for symptoms

Call your vet, an emergency animal hospital, or a pet poison helpline (in the US: ASPCA Animal Poison Control 888-426-4435 or Pet Poison Helpline 855-764-7661; in the UK: Animal PoisonLine 01202 509000). Have your dog’s weight and an estimate of how many grapes or raisins were eaten, and when, ready.

2. Do not induce vomiting at home unless a vet tells you to

Making a dog vomit incorrectly can cause aspiration pneumonia. Your vet may advise it if the grapes were eaten within the last hour or two, and will tell you exactly how.

3. Expect decontamination and fluids

At the clinic the vet will typically induce vomiting, give activated charcoal to bind remaining toxin, and start intravenous fluids for 48 hours to flush the kidneys and keep urine flowing. Blood tests check kidney values (creatinine, BUN, phosphorus) on arrival and again over the following 2–3 days.

4. Follow-up matters

Kidney damage can be delayed. Even if your dog seems fine, follow the vet’s advice on repeat blood tests.

Dogs treated within a few hours of eating grapes have an excellent prognosis. Dogs that arrive after kidney failure has developed may need days of intensive care, and some do not recover.

Can Dogs Eat Raisins?

No. Raisins are dried grapes, so the toxin is concentrated – a handful of raisins is roughly equivalent to a much larger quantity of fresh grapes. Raisin poisoning peaks around Christmas and Easter thanks to fruit cake, Christmas pudding, mince pies and hot cross buns. Keep these well out of reach and warn guests not to share.

Can Dogs Eat Grape Juice or Grape Jelly?

Avoid both. Juice and jelly contain the same compounds and are often loaded with sugar. Some “grape-flavoured” products contain no real grape at all, but check the label – and remember that sugar-free versions may contain xylitol, which is also highly toxic to dogs.

Safe Fruits Dogs CAN Eat

Plenty of fruits make healthy, low-calorie treats when served in moderation (treats should be no more than 10% of daily calories):

Blueberries – antioxidant-rich and perfectly bite-sized
Apple slices – remove the core and seeds
Banana – in small amounts (high in sugar)
Watermelon – seedless, rind removed
Strawberries – hulled and chopped
Cantaloupe melon – rind removed
Pear – core and seeds removed
Pumpkin – plain, cooked; great for digestion

Other foods that are toxic to dogs

While you’re dog-proofing the kitchen, remember these are also dangerous: chocolate, xylitol (in sugar-free gum and some peanut butters), onions, garlic, chives, macadamia nuts, avocado, alcohol, caffeine, cooked bones and raw yeast dough.

Frequently Asked Questions

My dog ate one grape – should I worry?

Yes, take it seriously. One grape is unlikely to harm a large dog, but it can affect a small dog or puppy, and there is no way to know in advance. Call your vet for advice – they may recommend inducing vomiting as a precaution.

How long after eating grapes will a dog get sick?

Vomiting often starts within a few hours; signs of kidney injury appear within 24 to 72 hours.

Can dogs eat seedless grapes?

No. The toxin is in the flesh of the grape, not the seeds, so seedless grapes are just as dangerous.

Are grapes toxic to cats too?

Grape toxicity is best documented in dogs, but there are reports in cats and ferrets. Don’t feed grapes or raisins to any pet.

Can dogs eat peeled grapes?

No. Peeling makes no difference – the toxic compounds are in the pulp.

Final Thoughts

So, can dogs eat grapes? Never. Treat grapes and raisins the way you would treat chocolate – keep them out of reach, warn the family, and if your dog gets hold of some, call the vet straight away rather than waiting to see what happens. Quick action almost always means a full recovery. For more on keeping your dog healthy for the long term, read our guide on how long dogs live and how to extend it.

How Long Do Dogs Live? Dog Lifespan by Size and Breed

How long do dogs live? On average, a dog lives 10 to 13 years – but that single number hides an enormous range. A Chihuahua can easily see its 16th birthday, while a Great Dane is considered elderly at seven. Size, breed, weight, diet and veterinary care all shape how many years you get with your best friend.

This guide covers the average dog lifespan, how long dogs live by size and breed, how to convert dog years to human years accurately, the most common causes of death in dogs, and the science-backed steps that add healthy years to your dog’s life.

Average Dog Lifespan

Large veterinary studies put the median lifespan of pet dogs at around 12 to 12.5 years. A 2024 study of more than 580,000 dogs in the UK found that small, long-nosed breeds live longest (a median of over 13 years), while flat-faced breeds such as Bulldogs and Pugs and giant breeds live the shortest.

The longest-lived dog with a verified record was Bluey, an Australian Cattle Dog who reached 29 years and 5 months. Most dogs won’t get anywhere near that, but with good care a 15- or 16-year-old dog is no longer a rarity.

How Long Do Dogs Live by Size?

Size is the strongest predictor of lifespan in dogs. Unusually among mammals, the bigger the dog, the shorter its life. Large dogs grow extremely fast as puppies, and researchers believe this accelerated growth speeds up ageing and increases cancer risk.

Size	Adult weight	Typical lifespan
Toy / small	Under 10 kg (22 lb)	12 – 16 years
Medium	10 – 25 kg (22 – 55 lb)	10 – 14 years
Large	25 – 45 kg (55 – 100 lb)	9 – 12 years
Giant	Over 45 kg (100 lb)	7 – 10 years

Dog Lifespan by Breed

Longest-living dog breeds

Chihuahua – 14 to 16 years
Toy and Miniature Poodle – 14 to 18 years
Dachshund – 12 to 16 years
Jack Russell Terrier – 13 to 16 years
Shih Tzu – 10 to 18 years
Yorkshire Terrier – 13 to 16 years
Lhasa Apso – 12 to 15 years
Australian Cattle Dog – 12 to 16 years
Border Collie – 12 to 15 years
Beagle – 12 to 15 years

Popular medium and large breeds

Labrador Retriever – 11 to 13 years
Golden Retriever – 10 to 12 years
German Shepherd – 9 to 13 years
Boxer – 10 to 12 years
Cocker Spaniel – 12 to 15 years
Siberian Husky – 12 to 14 years

Breeds with the shortest lifespans

Irish Wolfhound – 6 to 8 years
Great Dane – 7 to 10 years
Bernese Mountain Dog – 7 to 10 years
Mastiff – 6 to 10 years
Saint Bernard – 8 to 10 years
English Bulldog – 8 to 10 years
French Bulldog – 9 to 11 years

Mixed-breed dogs generally live slightly longer than purebreds of the same size, thanks to greater genetic diversity and a lower risk of inherited disease.

Dog Years to Human Years

The “one dog year equals seven human years” rule is a myth. Dogs age fastest in their first two years and then slow down – and larger dogs age faster than small ones. A more accurate guide:

Dog’s age	Small dog	Medium dog	Large dog	Giant dog
1 year	15	15	15	14
2 years	24	24	24	22
5 years	36	37	40	45
8 years	48	51	55	64
10 years	56	60	66	79
13 years	68	74	82	100
16 years	80	87	99	–

So a 10-year-old Chihuahua is a spry 56 in human terms, while a 10-year-old Great Dane is closer to 80.

What Do Dogs Usually Die Of?

Cancer – the leading cause of death in dogs over 10, especially in Golden Retrievers, Boxers and Bernese Mountain Dogs.
Heart disease – mitral valve disease in small breeds, dilated cardiomyopathy in large breeds.
Kidney failure.
Musculoskeletal decline – severe arthritis and loss of mobility, particularly in large dogs.
Bloat (GDV) – a life-threatening emergency most common in deep-chested breeds.
Trauma – road accidents remain a major cause of death in younger dogs.

How to Help Your Dog Live Longer

1. Keep your dog lean

A landmark 14-year Purina study found that dogs fed to a lean body condition lived almost two years longer than their overweight littermates and developed arthritis and other chronic diseases much later. Being able to feel (but not see) your dog’s ribs is the goal.

2. Exercise every day

Daily walks and play keep muscles strong, joints mobile, weight under control and minds sharp. Adjust intensity to your dog’s age and breed.

3. Feed a complete, balanced diet

Choose a food that meets AAFCO or FEDIAF standards for your dog’s life stage and size. Large-breed puppies need specially formulated food to slow their growth and protect their joints.

4. Don’t neglect dental care

By age three most dogs have some dental disease. Bacteria from infected gums enter the bloodstream and damage the heart, liver and kidneys. Brush regularly and schedule professional cleanings.

5. Keep up with preventive vet care

Vaccinations, parasite control, annual check-ups and – for seniors – twice-yearly blood tests catch problems while they are still treatable.

6. Spay or neuter at the right time

Neutered dogs live longer on average, but for large breeds timing matters – talk to your vet about waiting until growth is complete.

7. Protect against accidents

Lead walks near roads, secure fencing, and keeping toxic foods (see why dogs must never eat grapes) and medications out of reach prevent the most common avoidable deaths.

8. Keep the brain busy

Training, scent games and puzzle toys slow cognitive decline in senior dogs – the canine equivalent of dementia is very real.

Signs Your Dog Is Getting Old

A greying muzzle is the obvious one, but also watch for slower walks, stiffness after rest, cloudy eyes, hearing loss, weight change, more sleep, new lumps, bad breath, and confusion or restlessness at night. None of these should be dismissed as “just old age” – most have treatments that improve quality of life.

Frequently Asked Questions

Can a dog live 20 years?

Rarely, but yes – a handful of small dogs, usually Chihuahuas, Dachshunds and terriers, reach 20. It requires good genetics, a lean body and excellent care.

Why do small dogs live longer than big dogs?

Large dogs grow extremely fast, which appears to accelerate cell ageing and raise cancer risk. They also carry more strain on their hearts and joints.

Do mixed-breed dogs live longer?

On average, yes – by roughly a year compared with purebred dogs of the same size, thanks to lower rates of inherited disease.

At what age is a dog considered a senior?

Small dogs at 10–12, medium dogs at 8–10, large dogs at 6–8 and giant breeds from around 5–6 years old.

Final Thoughts

How long dogs live depends mostly on size and genetics – but the factors you control add up to years, not months. Keep your dog lean, active, vaccinated and dentally healthy, and you dramatically improve the odds of many happy years together.

How Long Do Cats Live? Average Cat Lifespan (Indoor vs Outdoor)

If you share your home with a cat, sooner or later you ask the question every cat lover dreads and hopes about at the same time: how long do cats live? The short answer is that a well-cared-for indoor cat typically lives 12 to 18 years, and it is no longer unusual for cats to reach their early twenties. The longer answer depends on where your cat lives, what it eats, its breed, and the quality of veterinary care it receives.

In this guide we break down the average cat lifespan, why indoor cats live so much longer than outdoor cats, how to convert cat years to human years, which breeds tend to live longest, and – most importantly – what you can do today to give your cat the longest, healthiest life possible.

How Long Do Cats Live on Average?

Across all cats, the average lifespan is usually quoted as 13 to 17 years. A large UK study by the Royal Veterinary College that reviewed the records of thousands of cats found a median lifespan of around 14 years, with crossbred (moggy) cats living slightly longer on average than pedigree cats.

That average hides a huge range. Some cats are lost to illness or accidents before they turn five, while others are still climbing onto laps at 20. The oldest cat ever recorded, a Texas cat named Creme Puff, lived to an astonishing 38 years.

Type of cat	Typical lifespan
Indoor-only cat	12 – 18 years (often 20+)
Indoor/outdoor cat	10 – 14 years
Outdoor-only / free-roaming cat	2 – 5 years on average
Feral cat	2 – 5 years

Indoor vs Outdoor Cats: Why the Difference Is So Big

The single biggest factor in how long a cat lives is whether it spends its life indoors or outdoors. Indoor cats routinely live two to three times longer than cats that roam freely. The reasons are not mysterious:

Road traffic – the leading cause of death for young outdoor cats.
Infectious disease – feline leukaemia (FeLV), feline immunodeficiency virus (FIV) and upper-respiratory infections spread through fights and contact with other cats.
Parasites – fleas, ticks, worms and the illnesses they carry.
Predators and fights – dogs, foxes, coyotes and other cats.
Poisons – antifreeze, rodent bait, lilies, slug pellets and pesticides.
Extreme weather and getting lost or trapped.

That does not mean an indoor cat has to be bored. Window perches, cat trees, puzzle feeders, daily play sessions and a secure “catio” or harness walks give your cat the stimulation of the outdoors without the danger. If your cat seems restless or unhappy indoors, our guide to the signs your cat is stressed explains what to look for.

Cat Years to Human Years

The old “multiply by seven” rule is wrong for cats. Cats mature very quickly in their first two years and then age more slowly. Veterinary associations use this conversion:

Cat’s age	Human equivalent	Life stage
6 months	10 years	Kitten
1 year	15 years	Junior
2 years	24 years	Young adult
5 years	36 years	Adult
7 years	44 years	Mature
10 years	56 years	Senior
15 years	76 years	Geriatric
20 years	96 years	Geriatric

A simple way to remember it: the first year counts as 15 human years, the second adds 9 (so a two-year-old cat is about 24), and every year after that adds roughly 4 human years.

How Long Do Cats Live by Breed?

Genetics matter. Mixed-breed cats tend to be the hardiest, but among pedigree cats there are clear patterns:

Longest-living cat breeds

Siamese – 15 to 20 years
Burmese – 16 to 18 years, with many reaching 20+
Balinese – 15 to 20 years
Russian Blue – 15 to 20 years
Ragdoll – 15 to 18 years
Sphynx – 13 to 15 years

Breeds with shorter average lifespans

Maine Coon – 12 to 15 years (prone to hypertrophic cardiomyopathy)
Bengal – 12 to 16 years
Persian – 12 to 15 years (breathing and kidney issues)
Scottish Fold – 11 to 14 years (cartilage disorders)
Abyssinian – 9 to 15 years

Remember these are averages: an individual cat’s care and luck matter more than its pedigree.

What Do Cats Usually Die Of?

Understanding the most common age-related illnesses helps you catch them early, when treatment makes the biggest difference:

Chronic kidney disease – affects around a third of cats over 12. Early signs are increased thirst and urination, weight loss and a dull coat.
Cancer – lymphoma is the most common type in cats.
Hyperthyroidism – an overactive thyroid causing weight loss despite a huge appetite.
Heart disease – especially hypertrophic cardiomyopathy.
Diabetes – strongly linked to obesity.
Dental disease – painful, and bacteria from the mouth can damage the kidneys and heart.

8 Ways to Help Your Cat Live Longer

1. Keep your cat indoors (or safely enclosed)

Nothing else on this list comes close. An indoor lifestyle removes almost every major cause of early death.

2. Spay or neuter

Neutered cats live longer: they roam and fight less, and they avoid cancers of the reproductive organs and uterine infections.

3. Keep your cat at a healthy weight

Over half of pet cats are overweight. Obesity roughly doubles the risk of diabetes and worsens arthritis and heart disease. Measure meals, limit treats to 10% of daily calories and use play to burn energy.

4. Feed a complete, high-quality diet

Cats are obligate carnivores. Choose a food that meets AAFCO or FEDIAF standards and includes plenty of animal protein. Wet food helps cats stay hydrated, which supports the kidneys.

5. Encourage drinking

Many cats drink too little. Place several water bowls around the home, keep them away from food and litter, and consider a pet fountain – moving water is far more appealing to cats.

6. Never skip the vet

Annual check-ups for adult cats and twice-yearly visits for seniors (over 10) allow your vet to catch kidney disease, thyroid problems and dental disease before they become life-threatening. Keep vaccinations and parasite prevention up to date.

7. Look after their teeth

Daily brushing with a cat toothpaste, dental treats and professional cleanings prevent the chronic infection that silently shortens many cats’ lives.

8. Reduce stress and keep the mind active

Chronic stress weakens the immune system and contributes to bladder problems. Provide hiding places, vertical space, scratching posts, daily play and a predictable routine.

Signs Your Cat Is Getting Old

Cats hide illness well, so watch for subtle changes: sleeping more, reluctance to jump, weight loss or gain, drinking more, a matted or greasy coat, bad breath, cloudy eyes, confusion or crying at night. Any of these deserve a vet visit – many are treatable.

Frequently Asked Questions

Can a cat live to 20?

Yes. Reaching 20 is increasingly common for indoor cats that are neutered, kept lean and see the vet regularly. Cats over 20 are considered “super seniors”.

How long do indoor cats live?

Most indoor cats live 12 to 18 years, and many live into their early twenties.

How long do outdoor cats live?

Cats that live entirely outdoors average only 2 to 5 years because of traffic, disease, predators and poisoning.

Do male or female cats live longer?

Female cats live slightly longer on average, but neutering narrows the gap considerably – neutered males live far longer than intact males.

What is the oldest cat ever?

Creme Puff, from Austin, Texas, lived from 1967 to 2005 – 38 years and 3 days.

Final Thoughts

So, how long do cats live? Long enough to become a true member of the family – typically 12 to 18 years, and often beyond. You can’t control genetics, but you can control the two things that matter most: keeping your cat safe indoors and staying on top of preventive veterinary care. Do those, and you give your cat the best possible chance of celebrating its twentieth birthday with you.

8 Signs Your Cat Is Stressed and How to Help

Recognising the signs cat is stressed can feel tricky because cats are masters at hiding discomfort. Unlike dogs, who wear their emotions openly, cats tend to suffer in silence until things get really bad. The good news is that once you know what to look for, you can step in early and make a real difference for your cat.

Stress in cats is more common than most owners realise. Changes in routine, new pets, loud noises, or even rearranging furniture can tip a sensitive cat over the edge. Learning to read your cat’s subtle signals means you can act fast and keep them feeling safe and settled.

1. Hiding More Than Usual

Every cat enjoys a quiet nap in a tucked-away spot, but if your cat is suddenly spending most of the day hiding and refusing to come out, that is one of the clearest signs cat is stressed. A stressed cat will seek out small, dark, enclosed spaces where they feel invisible and safe. Think under beds, inside wardrobes, or behind sofas.

The key difference between normal hiding and stress-related hiding is duration and frequency. A relaxed cat hides for a snooze and then comes back out to interact. A stressed cat may stay hidden for hours or even full days at a time.

If your cat has started hiding after a specific event, like moving house, a new baby arriving, or a new pet joining the family, that context is a big clue. Try not to force them out, as that will only increase anxiety. Instead, place their food and water nearby and give them space to emerge on their own terms.

2. Changes in Litter Box Habits

One of the most noticeable signs cat is stressed is a sudden change in litter box behaviour. This can mean going outside the box, going more frequently, or straining to urinate. Any change from your cat’s normal habits deserves attention.

Stress can directly cause urinary issues in cats, particularly in male cats who are prone to feline idiopathic cystitis (FIC). This condition is triggered by stress and causes inflammation of the bladder, making urination painful. If your cat is visiting the litter box repeatedly and producing little or no urine, treat it as an emergency and contact your vet immediately.

For less urgent litter box changes, consider whether the box is clean enough, positioned in a quiet spot, and whether the type of litter has changed recently. Cats can be sensitive about all of these things. The American Association of Feline Practitioners recommends one litter box per cat plus one extra as a general rule.

3. Increased Grooming or Bald Patches

Over-grooming is a stress response that many owners mistake for normal cat behaviour. Signs cat is stressed through grooming include licking one area repeatedly, chewing at the fur, or pulling hair out entirely. You might first notice thinning patches on the belly, inner legs, or the base of the tail.

This behaviour is called psychogenic alopecia and it is essentially a self-soothing mechanism. The repetitive motion of grooming releases endorphins, so stressed cats will do it to excess as a way of coping with anxiety. Unfortunately it can quickly lead to raw skin and secondary infections.

If you spot bald patches or irritated skin, get your vet to rule out any skin condition or parasites first. Once those are ruled out, the focus shifts to identifying and reducing the stress trigger. Environmental enrichment, calming pheromone diffusers, and sometimes anti-anxiety support from your vet can all help significantly.

4. Signs Cat Is Stressed Through Aggression

A normally calm cat that starts hissing, swatting, or biting without obvious provocation is almost certainly stressed. Aggression is one of the more alarming signs cat is stressed because it can come out of nowhere and feel completely out of character. It is important not to punish this behaviour, as that will only make the underlying anxiety worse.

Redirected aggression is particularly common. This happens when your cat sees something that upsets them, like another cat outside the window, and then redirects that frustration onto you or another household pet. Understanding this helps you respond with empathy rather than frustration.

Identify what is triggering the aggressive episodes and try to remove or reduce that trigger. For cats reacting to outdoor cats, frosted window film on lower windows can help enormously. If your cat is struggling to live peacefully alongside other animals, this guide on cats living comfortably with other pets has some practical advice worth reading.

5. Loss of Appetite or Overeating

A stressed cat may stop eating altogether or, less commonly, start stress-eating far more than usual. Either pattern is a concern. Going without food for more than 24 to 48 hours puts cats at risk of hepatic lipidosis, a serious liver condition that develops quickly in cats who stop eating.

If your cat is suddenly turning their nose up at food they normally love, stress is a real possibility but it is always worth a vet check to rule out pain or illness first. Cats are good at masking physical discomfort, so a change in appetite can be a sign of several different problems.

Try warming food slightly to increase its aroma, or offer a different texture to tempt them back to eating. A calm, quiet feeding area away from loud appliances or other pets can also reduce mealtime anxiety considerably.

6. Excessive Vocalisation

Cats communicate in lots of ways, and understanding how cats communicating their needs works can help you tune into what your cat is trying to tell you. When a previously quiet cat suddenly starts meowing constantly, yowling at night, or crying loudly for no obvious reason, stress is often behind it.

Some breeds, like Siamese and Bengals, are naturally more vocal. But a notable increase in vocalisation from any cat, regardless of breed, is worth paying attention to. Night-time yowling in older cats can also point to cognitive dysfunction or hyperthyroidism, so a vet visit is sensible.

Try to respond calmly and consistently without reinforcing the behaviour with excessive fussing, which can accidentally reward the anxiety. Providing more interactive play sessions, puzzle feeders, and structured one-on-one time can help reduce the underlying restlessness driving the vocalisation.

7. Scratching Furniture and Destructive Behaviour

Scratching is completely natural for cats, but an increase in destructive scratching or other out-of-character behaviour like knocking things over repeatedly is one of the signs cat is stressed. Cats scratch to mark territory, and a stressed cat will scratch more to try to reclaim a sense of security in their space.

Make sure your cat has at least two good scratching posts available, ideally in the areas they are already targeting. Tall, sturdy sisal posts tend to be the most satisfying for cats. Placing one near a window can also give them a vantage point, which helps reduce general anxiety.

If the destructive behaviour has spiked, think about what has changed in your home recently. New furniture, a change in your work schedule, building work nearby, or even a new scent in the house can all unsettle a cat. Small environmental tweaks often make a surprising difference.
