CatYearsHow long do cats live?
The commonly cited range for an indoor cat is about 12–18 years. Cats that roam freely outdoors live, on average, far shorter lives — the gap is one of the largest in pet care, and it comes from traffic, predators, fights, disease and weather rather than from ageing itself.
Indoor vs outdoor, honestly stated
Indoor cats: roughly 12–18 years is the range most veterinary references give, and reaching the late teens is unremarkable for a healthy indoor cat. Free-roaming outdoor cats are often quoted at only about 2–5 years on average — that figure describes fully outdoor and feral cats exposed to every risk at once, and it varies a lot by place. Cats with supervised outdoor access or a secure garden sit somewhere in between. These are population averages, not predictions: any individual cat can land well outside them.
Rough breed ranges
Breed plays a smaller role for cats than for dogs, but it plays some. The ranges below are the broad figures commonly cited by breed and veterinary references — treat every one as a rough range, not a promise. Mixed-breed cats, which make up the large majority of pets, tend towards the longer end.
| Breed | Rough typical lifespan (approximate) |
|---|---|
| Domestic shorthair / mixed breed | ≈ 12–18 years |
| Siamese | ≈ 15–20 years |
| Ragdoll | ≈ 12–17 years |
| British Shorthair | ≈ 12–17 years |
| Persian | ≈ 12–17 years |
| Bengal | ≈ 12–16 years |
| Maine Coon | ≈ 10–13 years |
| Sphynx | ≈ 8–14 years |
Ranges are approximate and drawn from commonly published breed references; body condition, genetics and care move any individual cat well within — or beyond — them.
What actually moves the number
- Where the cat lives. Indoor life removes the biggest killers of young and middle-aged cats in one step.
- Weight. Obesity is linked with diabetes and joint and liver problems; a lean cat tends to outlive an overweight one.
- Teeth. Dental disease is extremely common in older cats and quietly affects eating, comfort and organs.
- Preventive care. Vaccination, parasite control, neutering, and — for seniors — twice-yearly check-ups that catch kidney and thyroid disease early.
- Luck and genetics. Some of the spread is simply not controllable, which is why this page deals in ranges.

Common questions
What is the oldest a cat can live?
Exceptional cats pass 25, and the verified record is 38 years (Creme Puff, of Texas). Those are outliers, not targets — the late teens are already a long, full life.
Do neutered cats live longer?
Neutered cats are commonly reported to live longer on average, largely because they roam less, fight less and avoid reproductive diseases. It is one of the simpler lifespan levers available.
Is 15 old for a cat?
Yes — 15 is the start of the Geriatric stage, about 76 in human years. Plenty of 15-year-olds are comfortable and content, but they benefit from senior-focused care.
