Cat Friendly Clinic – Changing Your Cat’s Food


Why do you need to change your cat’s food?

Your vet may recommend your cat is fed a different or special diet.
This may be to help, for example, in:
• Controlling a specific disease (eg, diabetes or kidney
• Controlling your cat’s weight
• Tempting an inappetent cat to eat
• Improving recovery from surgery or illness
• Improving your cat’s diet based on its age and needs
How to change your cat’s food
Some cats develop strong preferences for certain foods, but
following a few simple tips can make changing the diet much
easier. Always follow your vet’s advice on how to introduce a
new diet, but in general:
• Make the change to a new diet gradual over 3–7 days (or
even longer if you have a very fussy cat)
• Start by mixing a small amount of the new diet with the old
• If your cat accepts the new diet, gradually increase the
amount of the new and decrease the amount of the old
diet over several days until only the new diet is being fed
• If your cat is reluctant to take the new diet, make the
change more gradual, over a longer period
• If using wet (tinned or sachet) food, warm it slightly (to body temperature) to enhance palatability
• If done gradually, most cats accept a change in diet, but talk to your vet if you need any further help or advice
