My Cat Is Not Eating: When to Call and What to Tell the Vet

If your cat stops eating or eats much less than usual, contact your veterinary team promptly. Avoid spending several days trying new flavors before asking for help. Cornell Feline Health Center notes that a sustained loss of appetite can seriously affect an adult cat in as little as 24 hours; very young kittens can deteriorate sooner. This is a warning about risk, not permission to wait 24 hours.

First, work out what was actually eaten

An empty bowl and a full bowl can both be misleading in a household with several animals. Another cat may have finished the meal, or the portion may have been topped up without anyone recording it. Tell the clinic what you can confirm, and say when you are unsure.

Useful details include the last normal meal, the approximate amount eaten since then, whether your cat approaches food and turns away, and any trouble picking up or chewing it. Include treats, too. Eating two treats does not necessarily mean a cat has eaten an adequate meal.

Keep the call short and specific

You could say: “My cat last ate a normal dinner yesterday evening. This morning they sniffed breakfast but ate very little. I have also noticed hiding. What should I do now, and where should I go if your clinic is closed?”

Add your cat's age, known health conditions, current medicines and any vomiting, diarrhea, changes in drinking or difficulty urinating. Breathing difficulty, collapse, severe weakness or suspected poisoning warrants urgent veterinary attention. Call an emergency hospital if needed.

Appetite loss has more than one explanation

Cornell describes appetite loss as a sign with many possible causes, including illness, pain and changes in a cat's surroundings. A food preference cannot establish the cause. A cat who seems interested in dinner may still need an examination.

Keep familiar food available as advised by the clinic, in a quiet place where you can observe intake. Do not force food into your cat's mouth or start an appetite medicine without veterinary instructions. Cornell explains that force-feeding can create a negative association with food.

During a planned food change

Stop treating the situation as a test of determination. Ask your veterinarian what to offer next and how quickly your cat needs assessment. Our food-transition article covers routine changes for otherwise well pets; it does not replace care for a cat who has stopped eating.

Record the clinic's next step and the time you should call again if intake remains low. A clear plan is more useful than collecting a growing row of unopened food bags.
