Bengal Cat Lifespan: What Was Measured, and What Gets Repeated
Two UK studies measured Bengal life expectancy at 8.5 and 7.3 years; every registry prints 12 to 16 with no study behind it. Both sets of numbers, with their samples and caveats.

Two kinds of numbers circulate about Bengal lifespan, and they disagree by several years. The measured kind comes from studies that counted real deaths. The quoted kind is a range no source has ever attached a study to. You deserve both, in that order.
The measured figures, with their samples
The largest dataset is UK , 2024. From 73 Bengal deaths among 7,936 cats under primary veterinary care in 2019, it measured a life expectancy at birth of 8.51 years (95 percent confidence interval 7.12 to 9.90). That is the second-shortest of the twelve breed groups analyzed, above only the Sphynx, against 11.74 years for all cats. Thirteen years earlier, the same research program's 2015 study measured a Bengal median age at death of 7.3 years, from 15 cats, the shortest in its table.
Two studies, thirteen years apart, same direction. And then the honest complication. A Swedish study of insured cats (1999 to 2006, 40 Bengal deaths) found the OPPOSITE: the joint-lowest mortality rate in its table, with a confidence interval (7 to 562 per 10,000 cat-years) so wide it barely constrains the answer. Different country, an insured and generally better-resourced population, a different era. The question is genuinely unsettled. The two UK studies agree with each other, and nothing else agrees with them.
The quoted range, labeled honestly
"12 to 16 years" appears on 's page, 's, PetMD's and WebMD's, word-identical, with no study cited by any of them. Purina UK says 10 to 16 and says 12 to 20, also uncited. That is one convention with two outliers, not six independent findings. We publish it as what it is: a commonly cited estimate, no measured study exists behind it.
What might explain the gap
Three things worth knowing before drawing conclusions. First, the UK figures measure real veterinary populations where 83.7 percent of recorded deaths were euthanasia decisions. They track when owners and vets end suffering, not pure biology. Second, in the 2024 study, being purebred (1.83 times the odds of death before age 3) and being unneutered (4.29 times) both shortened lifespan across breeds.
The study does not isolate what is Bengal-specific. Third, the "hybrid vigor" story you will meet on pet sites, that wildcat ancestry buys extra health, has no study behind it anywhere we searched. The two largest measured studies point the opposite way. No US, Canadian or Australian measured Bengal figure exists at all.
Living with the numbers
A number is not a destiny. The 2024 study's observed Bengal lifespans ran from 0.14 to 21.22 years, so long-lived Bengals exist in the very dataset that produced the low average. The practical reading is vigilance, not fatalism. Keep weight ideal (non-ideal body weight shortened lifespan across breeds in the 2024 model).
Neuter, insure early, and treat the breed's heart screening seriously (the health section of the pillar covers ). Cats are seniors at 10 by the and life-stage definitions, and a substantial share of the UK study Bengals died before reaching that stage. Twice-yearly vet checks from age 7 are cheap insurance. Something wrong with your cat means call your vet, out of hours an emergency clinic.

Frequently asked questions
How long do Bengal cats live?
Measured in the UK: life expectancy at birth of 8.51 years (73 deaths, 2019 data) and an earlier median of 7.3 years (15 cats). Commonly cited estimate: 12 to 16 years, no measured study exists behind it. A Swedish insured population pointed the other way, with a very wide confidence interval.
Why do Bengal lifespan numbers disagree so much?
Different populations: UK primary-care cats versus Swedish insured cats, samples of 15 to 73 deaths, and euthanasia decisions shaping the recorded ages. The two UK studies agree with each other across thirteen years.
Do Bengals live longer because of hybrid vigor?
No study supports that claim anywhere we searched, and the two largest measured studies place the Bengal near the bottom of the breed longevity table, not the top.
What is the oldest Bengal cat on record?
Guinness lists no Bengal longevity record: the oldest-cat-ever page (Creme Puff, 38) states no breed, and no Bengal appears in any longevity record we could open.

This is information, not veterinary advice, and it cannot tell you what is wrong with your cat. Our rule is a simple one: if something is wrong with your cat, call your vet, and call an emergency clinic if it is out of hours. Nothing you read here is a reason to wait.
Medical information applies to every reader. Prices, legal duties and common practice do not: unless stated otherwise, they are given for the United States, and they differ in the UK, Canada and Australia, and often between states or provinces. Check with your own vet and your own local authority.
