Food & water

How should I change my cat’s food?

Unless your vet advises otherwise, transition gradually by mixing increasing amounts of the new food with the old food over roughly seven days. Slow down if your cat develops mild digestive upset or refuses the mixture.

A good next step

  • Keep meal times predictable.
  • Do not starve a cat into accepting a new diet.
  • Seek veterinary advice if appetite drops or vomiting or diarrhoea persists.

Know when to stop searching

Some questions need a vet, not a webpage.

Seek urgent veterinary help for breathing difficulty, collapse, seizures, severe pain, major trauma, suspected poisoning, heatstroke, or repeated straining without passing urine.

If you are unsure, call your regular vet or nearest emergency veterinary clinic for triage.
