How should I feed my senior cat differently?
From about age 10 (the senior line), feeding is less about a 'senior food' label and more about closer monitoring: watch weight and appetite tightly, keep food and water easy to reach for stiffer joints, and let your vet — not the bag — decide any therapeutic diet.Fact
Age-related changes often begin at 7–10, and joint disease makes access harder. Any prescription or weight-management diet is a veterinary decision.
Applies to: Cats roughly 10+ (or 7–10 showing changes) on maintenance feeding. Therapeutic/prescription diets are set by your vet.
Steps
Monitor more, guess lessFact
- Seniors (10+) need twice-yearly vet exams; weight and appetite are the home metrics between them
- Age-related changes commonly begin 7–10 and are near-universal by 12
- Weigh monthly — senior weight change is an early flag, not a cosmetic one
Make eating easy on old jointsFact
- Arthritis (very common in seniors) makes reaching food/water/bowls harder
- Raise or reposition bowls; put food and water where no jump is needed
- Multiple stations so a stiff cat doesn't have to travel far
Leave the diet decision to the vetProfessional guidance
- Don't switch to 'senior' or therapeutic food on your own — your vet matches diet to your cat's health
- Bring your weight/appetite log to exams
- A senior that suddenly eats much more or less is a vet visit, not a diet tweak
Normal vs keep-watching
Normal: A senior holding steady weight, eating well, reaching food and water comfortably.
Keep watching: Monthly weight, appetite direction, and ease of getting to food/water (a joint-access clue).
When to contact a vet. A senior eating much more or less, losing weight, or drinking more needs a vet — these are common early senior-disease signs, and any therapeutic-diet decision is the vet's, never this page's.
