When is a cat a senior?
Cats are generally considered senior after 10 years of age, and many start showing age-related changes around then. With good care, indoor living and modern veterinary medicine, cats are living longer than ever, and age itself isn't a disease.
Twice-yearly vet checks
Older cats are good at hiding illness, so regular checks matter. Senior cats should see the vet twice a year or more, and exams may include bloodwork, a dental check and a blood pressure reading to catch common conditions like kidney disease, thyroid disease and diabetes early.
Signs to report
- Weight loss or a change in appetite
- Drinking or urinating more
- Going outside the litter box
- Sleeping more, hiding, or less interest in play
- Stiffness, reluctance to jump or a messier coat from grooming less
- Vocalizing more at night or seeming confused
- Bad breath or difficulty eating
Easy changes at home
- Litter boxes with lower sides, on every floor your cat uses
- Steps, ramps or a chair to reach favorite windowsills and beds
- Warm, padded beds away from drafts
- Food and water where your cat doesn't have to jump
- Gentle brushing to help with spots your cat can no longer reach

Questions, answered
How old is a senior cat in human years?
Cats are generally considered senior from about 10 years old. Cat-to-human age conversions are rough, but a 10-year-old cat is well into middle age.
Why is my old cat losing weight?
Weight loss in older cats is common with conditions like kidney disease, an overactive thyroid, diabetes and dental pain. Book a vet visit if your cat is losing weight.
Why is my senior cat peeing outside the litter box?
Medical problems and arthritis are common causes; high-sided boxes can be hard to climb into. See your vet, then try a low-entry box.
