One missed meal can happen, but a cat that stops eating may be in pain, nauseated, stressed, or seriously ill. Contact a veterinarian promptly when your cat refuses food, especially if it approaches 24 hours or any other symptoms appear. Very young kittens, sick cats, and cats with chronic conditions need help sooner.
Why appetite loss matters in cats
Cats can develop serious metabolic complications when they do not eat adequately. One concern is hepatic lipidosis, a liver condition associated with poor food intake, especially in overweight cats. Appetite loss can also result from dental pain, kidney disease, gastrointestinal illness, infection, medication effects, or changes in the home.
When to seek emergency care
Go to an emergency clinic if a cat who is not eating also has trouble breathing, collapses, has severe weakness, repeated vomiting, a painful swollen abdomen, or is unable to urinate. Call the veterinarian the same day for appetite loss accompanied by lethargy, dehydration, or other illness. A kitten who stops nursing or eating should be assessed urgently.
What to observe before calling
- When did your cat last eat a normal meal?
- Is the cat drinking, urinating, and using the litter box normally?
- Is there vomiting, diarrhea, hiding, drooling, or difficulty chewing?
- Has food, medication, household routine, or access to the bowl changed?
- Is there weight loss or a history of diabetes or kidney disease?
Safe steps while arranging an appointment
Offer the usual food in a quiet location and make sure fresh water is available. A different texture or slightly warmed wet food may tempt some cats, but do not spend days cycling through treats instead of seeking care. Do not force-feed or syringe-feed a resisting cat unless a veterinarian specifically instructs you; this can increase stress and create choking or aspiration risk.
Never give human appetite stimulants or leftover pet medication. Your veterinarian may prescribe nausea treatment, appetite support, or assisted feeding after identifying the cause.
What can an online vet do?
A remote consultation may help determine urgency and organize a history, but it cannot examine the mouth, evaluate hydration reliably, or perform tests. A cat that has stopped eating often needs a hands-on veterinary assessment.

Frequently asked questions
My cat is drinking but not eating. Can I wait?
Drinking does not rule out serious illness. Contact a veterinarian promptly, especially if food refusal is persistent.
Can stress make a cat stop eating?
Yes, but stress is a diagnosis of exclusion when appetite loss continues. A veterinarian can look for pain or disease.
Is a day without food dangerous?
It can be, particularly in kittens or sick cats. Cornell advises that sustained appetite loss can affect adult-cat health in as little as 24 hours.
