When a cat stops eating, it is more urgent than many owners realize. Cats that go without food for even a couple of days can develop serious liver problems, so a loss of appetite is worth acting on early. This guide is general information and not a diagnosis.
Why cats stop eating
- Stress: a move, a new pet, visitors, changes in routine or a new food
- Nausea or stomach upset
- Dental disease: painful teeth and gums make chewing hard
- Upper respiratory infections: a blocked nose reduces the sense of smell, which cats rely on to eat
- Kidney disease, liver disease, diabetes and hyperthyroidism
- Urinary problems
- Hairballs or a blockage
- Pain from arthritis or injury
- Medications or recent vaccination
- Food issues: a new brand, spoiled food or a dirty bowl
How long is too long?
Call a vet if your cat has not eaten for 24 hours, and sooner for kittens, seniors, overweight cats or cats with health conditions. A cat that stops eating can develop hepatic lipidosis, often called fatty liver disease, which needs veterinary treatment.
Red flags
- Vomiting or diarrhea
- Lethargy or hiding
- Not drinking, or drinking much more than usual
- Drooling, pawing at the mouth or dropping food
- Weight loss
- Straining in the litter box
- Open-mouth breathing, which is an emergency
What you can try at home
- Offer fresh food in a clean bowl, away from litter and noise
- Warm wet food slightly to boost the smell
- Try a small amount of a favorite food your vet approves
- Keep the environment calm
- Check the mouth and nose for obvious problems
Do not force-feed, and do not give human appetite medicine. Many human products are dangerous to cats.
What a vet may do
A vet may examine your cat, check the teeth, run bloodwork and other tests, and treat the cause. Some cats need fluids, anti-nausea medicine or appetite support while they recover.
Prevent appetite problems
Introduce new foods gradually, keep regular vet checkups, brush teeth and watch for changes early.
If your cat has stopped eating and you are unsure what to do, chat with a licensed vet on Waggle Vet any time. If your cat needs an exam, find a vet near me.
