Senior Cat Feeding Considerations

In short

Older cats can show changes in appetite, weight, and drinking, and feeding may need to adapt. This page covers general considerations to discuss with your veterinarian. It does not give diet advice for conditions such as kidney disease, thyroid disease, or diabetes — those require a veterinarian's assessment and, often, a prescription diet.

General considerations for older cats

  • Appetite and weight can change with age; gradual weight loss in an older cat is worth veterinary attention.
  • Hydration matters; some owners include wet food, and fresh water should always be available.
  • Dental discomfort can affect eating and food choice — ask your veterinarian.
  • Some seniors do well on their current food; others benefit from a change a veterinarian recommends.
  • Watch litter-box habits and drinking, which can change with age and health.

Planning checklist

  • Monitor weight and body condition more closely as your cat ages.
  • Note changes in appetite, drinking, chewing, or litter-box habits.
  • Keep fresh water available, and consider wet food for added moisture if appropriate.
  • Discuss whether the current food still suits your cat at routine visits.
  • Raise any persistent changes with your veterinarian promptly.

What not to assume

  • Do not assume increased thirst, weight loss, or appetite changes are just ageing — in cats these can signal conditions like kidney or thyroid disease or diabetes.
  • Do not choose a 'kidney', 'urinary', or other therapeutic diet on your own; these are veterinary decisions.
  • Do not let an older cat go without eating — it can be dangerous.
  • Do not change foods abruptly, especially with health concerns.

When to ask a veterinarian

Older cats benefit from prompt attention to changes. Ask a licensed veterinarian about the following.

  • Increased thirst or urination, weight loss, or appetite changes.
  • Any refusal to eat — even briefly — which is serious in cats.
  • Whether a therapeutic or prescription diet is appropriate for a diagnosed condition.
  • Whether the current food still suits your cat's life stage.
  • Before any significant diet change.

Senior Cat Feeding Considerations — Frequently Asked Questions

My senior cat is drinking more — should I change the food?
Increased thirst in an older cat can be a sign of a medical condition and should be assessed by a veterinarian rather than addressed by changing food on your own. See our page on cats drinking a lot of water.
Does my older cat need a special diet?
Some do and some do not. Therapeutic diets for conditions like kidney disease are veterinary decisions. Whether a general 'senior' food helps your cat depends on the individual and your veterinarian's assessment.
How do I keep an older cat hydrated?
Always provide fresh water, and some owners include wet food for added moisture. If you notice changes in drinking or urination, contact your veterinarian.
