Ragdoll

Life span: 12–17 yrs

• Hypertrophic cardiomyopathy (HCM) — the most important Ragdoll health risk: thickening of the heart muscle that can cause heart failure, clots, or sudden death. A breed-specific MYBPC3 mutation is testable; responsible breeders also screen breeding cats by echocardiogram. Buy only from cardiac-screened lines.
• Polycystic kidney disease (PKD) — inherited fluid-filled cysts that enlarge and impair the kidneys over years; a DNA test exists and screened lines should be clear, so ask for the parents' PKD-negative results.
• Bladder/urinary stones and FLUTD — Ragdolls are reported prone to lower urinary tract disease and stones; signs are straining, blood in urine, or going outside the box. Adequate water intake and prompt vet care matter.
• Feline infectious peritonitis (FIP) susceptibility — Ragdolls (often acquired young from catteries) are over-represented in FIP cases, a coronavirus-related disease; minimize stress and crowding in kittens and source from low-density, hygienic breeders.
• Gastrointestinal sensitivity / hairball obstruction — the semi-long coat plus a relaxed groomer means ingested hair; regular brushing and a fiber or hairball diet reduce vomiting and rare obstruction.
• Obesity-related joint and cardiac strain — not breed-unique but amplified here because the breed is large, food-motivated, and low-energy, and excess weight worsens the heart and joint risks above.

Siamese

Life span: 12–15 yrs

• Progressive retinal atrophy (PRA) — an inherited retinal degeneration causing gradual blindness; the Siamese is a classically affected breed and responsible breeders DNA- and exam-screen breeding cats.
• Amyloidosis (hepatic and renal) — abnormal amyloid protein deposits in the liver or kidneys leading to organ failure; a recognized familial problem in Siamese and Oriental lines and a defining breed health risk.
• Feline asthma / chronic bronchial disease — the Siamese is over-represented for allergic airway disease causing coughing and wheezing, often needing lifelong inhaled or oral medication.
• Progressive (Siamese-type) dental disease and gingivitis — the breed shows higher rates of early periodontal disease and gingivostomatitis, making routine dental care a recurring necessity rather than optional.
• Convergent strabismus and nystagmus — an inherited cross-eyed appearance and eye-flicker tied to the breed's pointed-coat genetics; usually cosmetic but a recognized breed trait.
• Vaccine-associated and mast cell tumors / mediastinal lymphoma — Siamese and related Oriental breeds show elevated rates of certain neoplasias, warranting prompt investigation of any new lump or breathing change.
