Cat Lifespan by Breed: Searchable Explorer

Last updated June 10, 2026

Every breed page on the internet will hand you a tidy lifespan range, and every one of those ranges deserves the same asterisk: it describes a typical, well-cared-for cat, not a promise about yours. The explorer below covers 44 breeds, including the Domestic Shorthair, the ordinary moggy that makes up the vast majority of pet cats, so you can search, filter, and sort the numbers. Just read them carefully. A range like 12–17 years means most cats of that breed who reach adulthood and get decent care land somewhere in that window; plenty fall outside it in both directions.

And here’s the part that matters more than any row in the table: for cats, lifestyle usually outweighs breed. An indoor cat kept at a healthy weight, with regular veterinary and dental care, will on average outlive an outdoor or overweight cat of any breed, often by years. Breed sets a loose baseline. How a cat lives does most of the rest.

No breeds match your search.

Why breed matters less in cats than in dogs

In dogs, breed is one of the strongest predictors of lifespan, and the main reason is size. A Chihuahua and a Great Dane are both dogs, but one weighs four pounds and the other can weigh a hundred and fifty, and big dogs age dramatically faster, with giant breeds often living roughly half as long as toy breeds.

Cats never made that trade. Nearly every domestic cat, pedigree or not, weighs somewhere between about six and eighteen pounds. The Maine Coon is the giant of the cat world, and it’s still only around three times the weight of a Singapura, nothing like the thirty-fold spread you see in dogs. So cats simply don’t have a small-versus-giant aging gap, and a breed’s size tells you very little about how long it will live.

The breed differences cats do show come from two places instead: inherited health conditions that selective breeding has concentrated in certain lines (heart disease in some, kidney disease in others), and extreme body types (flat faces, hairlessness, folded ears) that carry their own costs. That’s why the gap between long-lived and short-lived cat breeds is measured in a handful of years, not a doubling, and why the lifestyle factors above move the needle more than the pedigree does.

What the largest real-world dataset shows

The best evidence on how long cats actually live comes from the UK’s VetCompass programme, which analyses anonymised clinical records from first-opinion veterinary practices. In a 2024 study published in the Journal of Feline Medicine and Surgery, Teng and colleagues used those records to build the first life tables for companion cats in the UK, and the results are a useful reality check on breed-page numbers.

Overall, the study put life expectancy at age 0 at 11.7 years. Among the breeds with enough data to compare, Burmese and Birman cats came out longest-lived, at around 14.4 years, while the Sphynx was the shortest-lived at roughly 6.7 years, a finding consistent with the elevated rate of heart disease reported in the breed. And in a quiet win for the ordinary moggy, crossbred cats slightly outlived purebred cats on average.

If 11.7 years sounds low next to the 12–18 ranges in our table, that isn’t a contradiction; it’s a different measurement. Life expectancy at birth, calculated from veterinary records, averages over every cat: the kittens lost to infectious disease, the young cats killed in road accidents, the early deaths of every kind. Those losses pull the average down hard. The “typical lifespan” ranges quoted on breed pages, including ours, describe something else: roughly where a cat tends to end up once it has made it through to adulthood with ordinary care. Both numbers are true; they answer different questions. The same life tables show the encouraging flip side: a cat that has already reached its later years has more expected time remaining than the at-birth figure would suggest.

Breed-linked health conditions that shape these numbers

A few inherited conditions do most of the work of separating the breeds in this table, and they’re worth knowing by name.

Hypertrophic cardiomyopathy (HCM) is a thickening of the heart muscle and the most common heart disease in all cats. But Maine Coons and Ragdolls carry identified genetic mutations that raise their risk, which is why both breeds sit a little lower in the table than their sturdy builds might suggest. Responsible breeders screen their breeding cats with DNA tests and heart scans, so it’s a fair question to ask any breeder.

Polycystic kidney disease (PKD) mainly affects Persians and Persian-derived breeds such as the Exotic Shorthair and Himalayan. Fluid-filled cysts slowly crowd out working kidney tissue, typically showing up in middle age. A reliable DNA test exists, and the condition has become much rarer in well-screened lines.

Flat-faced (brachycephalic) anatomy, the look that defines the Persian, Exotic Shorthair, and Himalayan, narrows airways and crowds the eyes and teeth. It doesn’t carry a single dramatic lifespan penalty the way a heart condition can, but the breathing, eye, and dental problems add wear over a lifetime.

A handful of structural genes matter too: the Scottish Fold’s ear cartilage gene also causes painful joint disease, and the Manx tailless gene can produce spinal defects. None of this means a cat from these breeds is doomed (most live full lives), but it explains why their typical ranges sit where they do, and why screening questions are worth asking before you bring one home.

How to use this with the calculator

The explorer tells you what’s typical for a breed; the rest of this site helps you place your own cat on that curve. Start with the cat age calculator to convert your cat’s age into human years and find its current life stage. Knowing whether your cat is mature, senior, or geriatric matters more for day-to-day care than its breed does. From there, the cat life expectancy page walks through the factors you can actually control, and if your cat is ten or older, the senior cat check covers the changes worth flagging to your vet. Used together, the three tools turn a breed range from a piece of trivia into a care plan.
