How long do cats live? There is no single age that predicts an individual cat’s life. A 2024 Royal Veterinary College-linked study estimated life expectancy at birth at 11.74 years for cats in its UK veterinary dataset. Many individual cats live longer; an average is neither a deadline nor a maximum. Breed, age already reached, health and environment all matter.
What ‘life expectancy’ actually measures
The study analysed 7,936 confirmed cat deaths recorded through VetCompass between January 2019 and March 2021. Researchers used annual life tables to estimate average remaining years at different ages. The breed figures below are life expectancy at age zero, not median ages at death. They include the effect of deaths early in life; they do not tell you how many years an already healthy ten-year-old cat has left.
| Breed / group | Years (95% confidence interval) | Deaths analysed |
|---|---|---|
| Burmese | 14.42 (12.91–15.93) | 45 |
| Birman | 14.39 (12.87–15.91) | 38 |
| Crossbred | 11.89 (11.75–12.03) | 7,117 |
| Siamese | 11.69 (10.56–12.82) | 88 |
| Persian | 10.93 (9.63–12.23) | 80 |
| Ragdoll | 10.31 (8.86–11.76) | 69 |
| Maine Coon | 9.71 (8.42–11.00) | 69 |
| Bengal | 8.51 (7.12–9.90) | 73 |
| Sphynx | 6.68 (4.53–8.83) | 18 |
A confidence interval expresses uncertainty in the estimate. The Sphynx result, for example, comes from just 18 deaths and has a wide interval. Burmese and Birman estimates are almost identical and their intervals overlap substantially: this is not evidence that one guarantees a longer life than the other. The table lists selected groups, not every recognised breed or a global ranking.
12 cat lifespan facts worth understanding
- 1. The study’s overall life expectancy at birth was 11.74 years, not a universal maximum feline age.
- 2. Burmese cats had the highest estimate among the groups studied: 14.42 years, with considerable sampling uncertainty.
- 3. Birman cats followed at 14.39 years; the tiny gap between the two estimates should not drive a breed choice.
- 4. Crossbred cats had an estimate of 11.89 years at birth, compared with 10.41 years for purebreds pooled together.
- 5. Female cats had an estimated 12.51 years at birth; male cats had 11.18 years in this dataset.
- 6. That female–male difference was 1.33 years at birth; the gap narrowed among cats that had already reached older ages.
- 7. The Sphynx estimate was 6.68 years, but its small sample cannot explain an individual cat’s health or future.
- 8. Only 12 breed groups, including crossbreds, met the threshold of at least 15 deaths for separate life-table estimates.
- 9. Crossbred cats supplied 7,117 of the 7,936 recorded deaths, so some purebred estimates were based on much smaller samples.
- 10. Unneutered status was associated with higher odds of death before age three. An observational association is not proof of one cause.
- 11. Non-ideal body weight was associated with shorter recorded lifespan. Weight targets depend on the individual cat, not its breed average.
- 12. Life expectancy changes with age already survived. Subtracting a cat’s current age from the at-birth figure is not a valid life-table calculation.
Indoor cats, outdoor cats and why we do not invent a comparison
You may have seen neat claims that indoor cats live a particular number of years while outdoor cats live a much smaller number. The breed table above does not establish those figures. Outdoor access can involve traffic, fighting and other hazards, but housing, location and care vary. A responsible comparison needs a defined population and a comparable study, not two attractive numbers borrowed from unrelated websites.
What owners can take from the research
Use the study to ask better questions about health, not to count down a pet’s remaining years. A veterinarian can assess body condition, age-related changes and a care plan for your cat. Discuss weight, nutrition, dental health and neutering individually. If your cat is eating less, losing weight or behaving differently, its symptoms matter more than its breed’s table entry.
