The Russian Blue is a beloved cat breed with a wonderful temperament. But even healthy cat breeds face real health risks - heart disease, kidney problems, and dental issues can generate serious vet bills.
No breed-specific studies yet - unranked. Missing data is not low risk.
Measured risks
How often they happen is backed by published studies.
What is this?Hide
All cats [1] 14.7% (12.3-17.4%) point prevalence on screening echocardiography, 780 cats (Payne JR, et al. 2015, the CatScan study, J Vet Cardiol)
Thickened heart muscle that can cause sudden death without warning. No dedicated Russian Blue echocardiographic study exists - this is the all-cats screening baseline. Full profile →
What is this?Hide
All cats [2] 1.2% (cats under 9) rising to 3.6% (9 and older), UK primary care (Conroy M, et al. 2019, Veterinary Record/VetCompass). PKD1 is a documented Persian-lineage mutation (UC Davis VGL PKD test), not confirmed in Russian Blue genetic studies.
Progressive kidney failure requiring dietary management and fluid therapy. Some generic breed profiles list polycystic kidney disease for Russian Blues, but that mutation is documented in Persian-lineage breeds and hasn't been confirmed in Russian Blue genetic studies - this is the general all-cats, age-banded baseline instead.

Known risks
Well documented in the breed - but no study has counted how often.
What is this?Hide
All cats [3] 50-70% of cats over age 3 show some periodontal disease on exam (Lund EM, et al. 1999, JAVMA, general veterinary-practice population); no Russian Blue-specific prevalence study exists.
Periodontal disease requiring professional cleaning or extractions. No Russian Blue-specific study was found - this is the general all-cats baseline. Full profile →
What is this?Hide
Breed study Widely repeated across veterinary-content breed guides as the Russian Blue's most consistent health concern, tied to a food-motivated temperament; no controlled breed-specific obesity-prevalence study was found.
Russian Blues are frequently described as food-motivated 'chowhounds' - multiple breed health guides single out overeating and weight gain as the breed's single biggest practical health risk, since it's otherwise a naturally healthy, long-lived breed. Portion control matters more here than most breeds. Full profile →
What is this?Hide
Not measured No confirmed Russian Blue-specific prevalence found
Overactive thyroid causing weight loss, hyperactivity, and heart problems. No Russian Blue-specific prevalence study was found. Full profile →
What is this?Hide
Not measured No confirmed Russian Blue-specific prevalence found
Requires daily insulin. No Russian Blue-specific prevalence study was found, though the breed's obesity tendency is a known risk factor for diabetes generally. Full profile →
How we know these numbers
- Confirmed = measured or gene-confirmed specifically in this breed
- Breed study = scientists counted it in this exact breed
- Body type = comes from the cat's build - size, skull, skin
- Genetic risk = the gene is proven, the odds are not
- All cats = an average for all cats, not this breed
- Not measured = nobody has counted it yet

Similar cats
My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
