Senior Cat Care: What Changes After Age 10
Around age 10 a cat enters its senior years, and its needs quietly shift. This overview covers what to expect — from diet and mobility to the common diseases of older cats — plus the home changes and monitoring habits that help your cat stay comfortable and healthy for years to come.
Quick answer
Most cats are considered senior from around 10 and geriatric from about 15. Ageing itself is not a disease, but older cats develop specific conditions more often — kidney disease, hyperthyroidism, diabetes, dental disease and arthritis. The best care combines twice-yearly vet checks, watching for subtle changes at home, and small adjustments that keep everyday life easy.

What ageing looks like
Senior cats often sleep more, play less, and may lose muscle over the back and hind legs. Coats can look less groomed because arthritis makes twisting to groom uncomfortable. Some cats become clingier or more vocal, especially at night. None of this should be dismissed as "just old age" — many changes are treatable, and comfort improves markedly when the underlying issue is addressed.
Diet and hydration
Older cats can lose muscle and need good-quality, digestible protein unless a specific disease requires a therapeutic diet — for example a kidney diet, which must be vet-prescribed, never self-started. Hydration matters more with age; many senior cats do better on wet food, and a pet water fountain can encourage drinking. Sudden increases in appetite or thirst are important signs to report to your vet.

Making home easier
In a typical Hong Kong or Taiwan high-rise flat, small tweaks help a lot. Provide a litter box with a low entry so a stiff cat can step in easily, and keep food, water, litter and a warm bed on the same level so your cat need not climb. Ramps or steps up to a favourite windowsill, and soft warm bedding away from draughty air-conditioning, keep an achy cat comfortable.
Monitoring and vet checks
Because cats hide illness well, twice-yearly vet visits with blood and urine tests catch problems like kidney disease and hyperthyroidism before they become emergencies. Weigh your cat at home monthly; steady weight loss is one of the earliest and most reliable warning signs. Bring your log and any pet-camera clips of odd behaviour to appointments.

Quick FAQs
At what age is a cat a senior? Broadly, cats are senior from around 10 and geriatric from about 15, though individuals vary.
How often should a senior cat see the vet? Twice a year is the general recommendation, with blood and urine screening to catch common diseases early.
Is weight loss normal in old cats? No. Unexplained weight loss is one of the most important warning signs and always warrants a vet visit.
Should I switch my senior cat to a special diet? Only on veterinary advice. A healthy senior needs good protein and hydration; therapeutic diets are for diagnosed conditions and must be vet-prescribed.
