There is no reliable scientific ranking of the 13 healthiest cat breeds. Studies measure different things—such as estimated lifespan or the frequency of disorders recorded in a particular breed—and those results do not add up to one overall health score. The strongest comparable evidence here concerns lifespan in UK cats; it puts Burmese and Birman cats highest in one 2019 life-table analysis, but it does not show that either breed is healthiest in every sense.
That distinction matters if you are choosing a cat. Population averages can help frame questions, but they cannot predict an individual cat’s health. Use the evidence below to compare specific outcomes, then consider inherited risks, care needs, the individual cat, and the breeder’s health practices.
What does “healthiest cat breed” mean?
“Healthiest” could mean living longer, having fewer inherited conditions, experiencing fewer common disorders, or having care needs that are easier to meet. These are different questions. A breed may rank well for one outcome and still have a meaningful risk of a particular disease or welfare concern.
Veterinary population studies and breed-registry profiles also serve different purposes. Studies can estimate lifespan or describe disorders recorded in a studied population; registry pages offer breed and care guidance. Neither kind of evidence, on its own, establishes a universal ranking of overall health.

#1 Best Overall
Which cat breeds lived longest in a UK study?
A 2024 Royal Veterinary College VetCompass life-table analysis estimated life expectancy at birth for cats receiving primary veterinary care in the UK during 2019. Burmese and Birman cats had the highest estimates among the breed groups studied. These are population estimates for one place and period—not a forecast for an individual cat or a measure of total health.
| Breed or group | Estimated life expectancy at birth | Deaths included in the analysis |
|---|---|---|
| Burmese | 14.42 years | 45 |
| Birman | 14.39 years | 38 |
| Crossbred | 11.89 years | 7,117 |
| Ragdoll | 10.31 years | 69 |
These estimates come from the same UK study and refer to life expectancy at birth. The relatively small death counts for Burmese, Birman, and Ragdoll cats mean their estimates should be read with uncertainty. The much larger crossbred sample provides useful context, but the figures do not mean every crossbred cat will outlive every purebred cat.
Rank #2
The study also included Siamese, Persian, Norwegian Forest Cat, Maine Coon, Russian cats, British cats, Bengal, and Sphynx. Its outcome was lifespan, not a combined assessment of disease, welfare, or ease of care, so the results cannot establish that these—or any other named breeds—are among the “healthiest” overall. An earlier English mortality study found longer median longevity for crossbred cats than purebred cats overall, but its breed-specific figures had small samples for many breeds and should not be merged with the newer life-expectancy estimates.
What health findings are reported for Ragdolls?
A 2025 VetCompass study examined 2,025 Ragdolls under primary veterinary care in the UK during 2019, within a wider population of 1,254,484 cats. Periodontal disease was the most common precise-level disorder recorded in the Ragdoll group, with a prevalence of 8.84%. The study also reported signals involving haircoat disorder and enteropathy.
That 8.84% is the recorded prevalence within the studied Ragdoll population, not proof that Ragdolls have more periodontal disease than other cats. The authors did not conduct the full comparison with non-Ragdolls needed to establish formal comparative breed predisposition. Retrospective clinical records and incomplete data fields also limit what can be concluded.
On enteropathy, Professor Dan O’Neill and co-authors wrote: “These findings suggest the Ragdoll may be predisposed to enteropathy but do not confirm an aetiopathological pathway for such a predisposition.” In other words, the study raises a possible breed-related signal; it does not establish the cause or a definitive inherited mechanism.
What registry guidance says about Ragdolls
The Cat Fanciers’ Association (CFA) identifies hypertrophic cardiomyopathy as an inherited health issue in Ragdolls and notes that breeders test for it. CFA also cautions that food-motivated Ragdolls may be at risk of obesity. These are registry statements, not results from the population comparison described above. Ask a breeder what testing is done and how the results relate to the kitten’s parents; no screening result guarantees that a cat will remain healthy.
For coat care, CFA recommends regular combing with a steel comb to remove loose hair and tangles. Grooming supports coat maintenance; it does not prevent inherited disease.

Are American Bobtails especially healthy?
The International Cat Association (TICA) describes the American Bobtail as generally healthy, while noting that all cats can potentially develop genetic health problems. This is useful registry guidance, but it is not evidence that American Bobtails rank above other breeds in a comparative health study. TICA recommends brushing and routine care.
What can inherited-disease testing tell you?
A large 2022 genotyping study examined 11,036 cats: 10,419 pedigreed cats and 617 non-pedigreed cats. The authors identified 13 disease-associated variants in 47 breeds or breed types where those variants had not previously been documented. The finding supports asking informed, condition-specific questions about testing; it does not create an overall breed-health score.
A genetic test can look for a particular variant, but its meaning depends on the condition and the cat’s circumstances. A test is not a certificate of general health, and a negative result for one variant does not rule out every inherited or acquired problem. Ask the breeder and your veterinarian which tests are relevant to the breed and family history, what the result can establish, and what it cannot.
How to choose a cat using health evidence
- Decide which outcome matters. If you are comparing longevity, look for studies reporting the same measure and population. Do not treat lifespan as a substitute for disease prevalence or welfare.
- Ask about breed-specific risks. Request the names of relevant conditions, the parents’ screening results, and an explanation of what each test detects. A vague assurance that a line is “healthy” is less useful than condition-specific information.
- Consider everyday care. Factor in coat maintenance, dental care, feeding, and weight management. Registry guidance can identify practical needs, but it is not a comparative health ranking.
- Assess the individual cat. A breed average cannot tell you whether a particular kitten or adult cat is healthy. Discuss the cat’s health history and veterinary examination with a veterinarian.
- Plan for ongoing veterinary care. Choosing a breed or receiving reassuring genetic results does not replace routine preventive care or treatment when problems arise.
Why this is not a ranked list of 13 breeds
The evidence available for this topic does not compare thirteen breeds using one shared, validated measure of overall health. Filling a numbered list by combining a lifespan table, disease findings for one breed, and registry descriptions for others would imply a ranking the evidence cannot support. A more useful comparison keeps each claim attached to its actual outcome: Burmese and Birman had the highest estimated life expectancy in one UK analysis, while specific disorder and care information should be interpreted on its own terms.
