At what age is a British Shorthair considered senior?

Broadly, cats are classified as senior from around age 11. Given the British Shorthair's potential lifespan of 12-20 years, the senior phase can last many years -- making early preparation and regular veterinary monitoring especially worthwhile.

What health problems should I watch for in an aging British Shorthair?

Hypertrophic cardiomyopathy (HCM), polycystic kidney disease (PKD), chronic kidney disease, obesity (or conversely weight loss), and dental disease are the primary concerns for senior British Shorthairs. Annual bloodwork and urinalysis from around age 10-11 gives the best chance of catching these early.

Should I switch my senior British Shorthair to a senior-formula food?

A senior-formulated food with adjusted phosphorus and protein can benefit many older cats. If kidney disease has been diagnosed, a veterinary renal diet may be prescribed. Discuss the appropriate dietary change with your vet at the annual senior screening visit rather than making the switch independently.

My older British Shorthair is losing weight -- should I be worried?

Yes -- unexplained weight loss in a senior cat is always worth investigating. Common causes include dental pain, kidney disease, hyperthyroidism, diabetes, and other systemic conditions. Book a veterinary appointment promptly; most of these conditions are manageable if caught early.
