Cat Not Eating (Anorexia) Triage
Cats cannot safely go without food for long periods. A few days of not eating can trigger a life-threatening liver condition called Hepatic Lipidosis.
Go To Vet NOW
- The cat has eaten absolutely nothing for more than 24-48 hours.
- Not eating is accompanied by lethargy, weakness, or hiding.
- The cat goes to the food bowl, acts hungry, but refuses to eat or cries out in pain (could indicate severe dental issues or Feline Stomatitis).
- Not eating combined with vomiting or diarrhea.
- In kittens under 6 months old, not eating for even 12 hours is an emergency.
- Cats with underlying chronic conditions (CKD, Diabetes) who stop eating need immediate veterinary support.

Safe to Monitor at Home
- The cat skipped one meal but is acting normally otherwise.
- The cat is still eating some food, or treats, just less than normal (monitor closely).
- A recent diet change causing pickiness (though prolonged pickiness requires a vet visit).
In our experience
In our experience, trying to tempt a deeply nauseous cat with new foods will only create food aversions. If a cat is truly refusing all food, they need anti-nausea medication and potentially appetite stimulants from a vet.
