How do you treat a cat that has gone off her food but her behaviour is still the same as usual?

Answer 1

Make an appointment immediately and take the cat to the vet. There are myriad reasons a cat might stop eating, ranging from inconsequential to life-threatening. You can't know whether your cat has a minor ailment (such as a respiratory infection) or is in the beginning stages of a terminal illness, so it's always best to take the cat to the vet ASAP. Don't just "wait and see how it goes" because by then it may be too late.

This is especially true if this is an older cat we're talking about (over 8 years). That is the age when terminal illnesses usually begin to develop. Once a cat reaches 8 to 10 years of age, it becomes especially important to take the cat to the vet for a checkup at least once a year.

The most inconsequential reason I can think of would be dramatic changes in the household, such as drastic renovation or home improvement projects, moving to a new home, new people in the home, or family members leaving the home (such as kids going off to college or moving out on their own). Cats are notoriously averse to change of any kind, so major changes like these can put a cat off its food.

Unless you have had a major change in your household recently (which would probably account for the cat's behavior), I would take the cat to the vet. And again, it is especially urgent if this is an older cat.
