Russian Blue

Life span: 10–16 yrs

• Bladder/urinary stones (urolithiasis) — the most clinically relevant breed-realistic risk; stones or feline lower urinary tract disease cause straining, frequent small urinations, and blood in urine, and a urethral obstruction (more dangerous in males) is a true emergency. Adequate water intake, wet food, and weight control are the practical preventives.
• Obesity-linked type 2 diabetes — the Russian Blue is strongly food-motivated and readily overfed; resulting obesity is the breed's leading gateway to insulin resistance and diabetes mellitus, which then carries lifelong monitoring and treatment costs. This is largely management-preventable, which is precisely why it tops the practical list.
• Progressive retinal atrophy (PRA) — an inherited degeneration of the retina that gradually reduces and eventually eliminates vision; uncommon but reported in the breed, with no treatment, so it is a question to raise with any breeder about their lines.
• Dental (periodontal) disease — as in most cats, plaque and tartar lead to gingivitis, periodontal disease, and tooth loss; it is the most common avoidable health problem in an otherwise sound breed and responds well to home dental care plus periodic professional cleaning.
• Stress-related behavioral and over-grooming issues — not a structural disease, but the breed's documented sensitivity to household change and chaos can manifest physically as over-grooming, hiding, or litter-box avoidance, which owners should recognize as a health-relevant trait rather than mere shyness.

Life span: 14–15 yrs

• Polycystic kidney disease (PKD) — the defining inherited Persian risk: fluid-filled cysts progressively replace kidney tissue, often causing kidney failure in middle age. There is a definitive DNA test; buying from a PKD-tested line is the single most important purchase decision in this breed.
• Brachycephalic airway syndrome — the flat 'peke-face' restricts airflow, causing noisy breathing, exercise and heat intolerance, and in severe cases surgical correction; markedly worse in extreme show-type faces than in doll-face Persians.
• Excessive tearing and entropion / blocked nasolacrimal ducts — the shortened muzzle distorts tear drainage, causing chronic eye discharge, staining, and skin-fold infection; some Persians also have inward-rolling eyelids requiring surgery.
• Progressive retinal atrophy (PRA-pd, the Persian/early-onset form) — an inherited retinal degeneration leading to blindness, with a DNA test available for responsible breeders.
• Hypertrophic cardiomyopathy (HCM) — thickening of the heart muscle that can cause sudden decline; warrants periodic cardiac screening in adults.
• Dental malocclusion and crowding — the compressed jaw misaligns teeth, accelerating periodontal disease and making routine dental care a recurring cost.
• Coat matting and skin-fold dermatitis — not a genetic disease but a near-certain welfare problem without daily grooming, leading to painful pelting, sedated shave-downs, and infected facial folds.
