Persian

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.

British Shorthair

Life span: 12–17 yrs

• Hypertrophic cardiomyopathy (HCM) — the defining breed risk: thickening of the heart muscle that can cause heart failure, blood clots, or sudden death. Responsible breeders cardiac-ultrasound screen breeding cats; obesity in this food-motivated breed compounds the risk.
• Polycystic kidney disease (PKD) — inherited kidney cysts leading to progressive kidney failure, introduced into some lines via historical Persian outcrossing; a definitive DNA test exists and screened lines are essential.
• Obesity — not a genetic disease but the breed's single most common and most consequential health problem, because its placid, food-driven, low-activity nature makes weight gain near-default and directly worsens its cardiac and joint risks.
• Hemophilia B (Factor IX deficiency) — an inherited bleeding disorder documented in the breed; DNA-screenable in breeding cats and important to know before any surgery.
• Neonatal isoerythrolysis from blood-type incompatibility — the British Shorthair has a high frequency of blood type B, so blood-typing breeding cats prevents fatal newborn-kitten reactions and matters for any future transfusion.
• Gingivitis and periodontal disease — the breed shows a tendency to dental disease, making routine tooth brushing and dental checks a recurring necessity rather than optional.
