How Long Do Cats Live? Lifespan by Breed, Lifestyle, and Weight

Most pet cats live into their early to mid teens, and plenty reach 18 or 20. How long your own cat lives depends on breed, sex, weight, lifestyle, and how early health problems are caught.

Here is what recent research found, and the simple habits that give your cat the best chance at a long life.

What a study of 7,936 cats found

In 2024, researchers from the Royal Veterinary College in the UK and National Chung Hsing University in Taiwan published life tables for pet cats. They studied the records of 7,936 cats that died between 2019 and 2021, using data from VetCompass, a large database of UK vet clinic records.

The researchers also noted that some breeding practices used to create certain looks are linked to inherited health problems, such as heart defects, which can shorten lives.

Keep in mind that this figure is an average across all cats, including those that died young from accidents or illness. A healthy cat that reaches adulthood will often live well beyond 12.

Why some cats live longer than others

Weight

Extra weight raises the risk of diabetes, arthritis, and other problems, and the 2024 study found overweight cats tended not to live as long. Overweight cats are also at higher risk of a dangerous liver disease, hepatic lipidosis, if they ever stop eating.

Breed and genetics

Breeds with extreme features or small gene pools can carry inherited problems such as heart disease, breathing trouble from a flat face, and kidney disease. Mixed breed cats are not immune to illness, but they avoid some of these breed linked risks.

Lifestyle and safety

Cats that roam outdoors face traffic, fights with other cats, predators, poisons, and infectious diseases spread by contact. Indoor cats avoid most of these risks, but need daily play to stay fit and mentally healthy.

Vet care

Many common cat diseases, such as kidney disease, thyroid disease, and dental disease, develop slowly and quietly. Cats are also very good at hiding pain. Regular checkups and blood tests catch problems earlier, when treatment works better.

8 habits that help cats live longer

1. Keep your cat lean. Measure food, limit treats, and ask your vet for a target weight.
2. Feed a complete cat food. Cats have special needs. Dog food and homemade diets without a vet's input can leave gaps. See can cats eat dog food for why.
3. Encourage water. Wet food, water fountains, and several bowls around the house help.
4. Play every day. Two or three short sessions with a wand toy keep muscles strong and minds busy.
5. Keep up with vaccines and parasite control, based on your cat's lifestyle.
6. Take care of teeth. Dental disease is very common and painful. Ask your vet about checks and cleanings.
7. Make the home safe. Keep toxic plants such as lilies, medicines, and string out of reach. Use secure window screens.
8. Book regular checkups, yearly for adults and every six months for seniors.

Early warning signs to take seriously

Cats hide illness well, so small changes matter. Call your vet if you notice:

• Drinking or peeing more than usual
• Weight loss, even with a good appetite
• Eating less, or skipping meals (see when to worry about a cat not eating)
• Vomiting more than once in a while
• Hiding, sleeping more, or less interest in play
• A messy coat, which can mean pain or stiffness that makes grooming hard
• Peeing outside the litter box

Helping a senior cat stay comfortable

• Add steps or ramps to favorite high spots.
• Use a litter box with a low entry so stiff joints can step in easily.
• Put food, water, and litter on each floor of a multi level home.
• Offer soft, warm beds away from drafts.
• Brush your cat, since older cats often groom less.
• Ask your vet about pain relief. Arthritis is common and very treatable in cats.

Questions to ask at your cat's next checkup

Bring these to your next vet visit. The answers give you a clear plan for the years ahead:

1. What is my cat's ideal weight, and what body condition score is it now?
2. How much should I feed each day, including treats?
3. Which vaccines and parasite treatments fit my cat's lifestyle?
4. How do my cat's teeth look, and when is the next dental cleaning due?
5. Should we run blood and urine tests to set a healthy baseline?
6. Is my cat's blood pressure normal? This becomes more important after age 10.
7. What changes at home should make me call you sooner?

Write the answers down or ask for a printed summary. Comparing results year to year is one of the best ways to spot slow changes in kidney function, weight, and thyroid levels.

The bottom line

The average cat in the UK study lived about 11.74 years, but many cats live much longer with good care. Keep your cat at a healthy weight, feed a complete diet, play daily, and see the vet regularly. Watch closely for small changes, because cats rarely show they are sick until a problem is advanced.
