My cat is not eating: when to call a vet
A cat that stops eating needs prompt attention because appetite loss can reflect pain, nausea or serious illness and may lead to dangerous liver complications. Confirm the last normal meal, offer familiar food without force and contact a veterinarian the same day for sustained refusal.

My cat is not eating: when to call a vet — the quick answer
✓ Contact a veterinarian the same day for sustained food refusal
✓ Never force-feed unless a veterinary professional instructs you
✓ Kittens, seniors and cats with illness need earlier advice
✓ Breathing trouble, collapse or repeated vomiting is urgent
A missed snack is different from a cat refusing food. Because cats can become seriously unwell when they do not eat, appetite loss should be treated as a health sign—not a battle of wills.
Confirm how much was actually eaten
Separate pets for a monitored meal and measure what is offered and left rather than judging an apparently disturbed bowl. Record the last normal meal, treats, hunting or scavenging and whether the cat refuses everything or only one texture. Drinking does not make prolonged food refusal safe.
Watch what happens at the bowl
Approaching food then turning away, lip licking, drooling, swallowing repeatedly, food dropping, chewing on one side or sniffing without eating may suggest nausea or mouth pain. Also record vomiting, diarrhoea, constipation, thirst, urine, hiding, breathing and activity. A short natural meal video can help the clinic.
Offer familiar food without force
Provide a fresh small portion of the cat's usual complete food in a quiet place away from other pets. Slightly warming wet food may strengthen aroma. Keep fresh water available. Do not syringe-feed, smear food on the paws or mouth, or repeatedly present many rich foods unless a veterinary professional gives an individual plan.
Call the veterinary team promptly
Contact a veterinarian the same day when a cat stops eating or intake remains clearly reduced, and earlier for kittens, senior cats, cats with diabetes or other illness, and overweight cats. Sustained anorexia can accompany many diseases and may precede hepatic lipidosis, so do not wait several days for hunger to win.
Recognise emergency combinations
Seek urgent care for breathing difficulty, collapse, marked weakness, pale or yellow gums, severe pain, repeated vomiting, a swollen abdomen, inability to swallow, suspected toxin or string, or straining with little or no urine. Do not delay transport to tempt the cat with another meal.
Bring a useful timeline
List food and approximate amounts, medications, recent diet or household changes, weight trend and the last normal stool and urine. Bring relevant packaging or exposure evidence. Follow the clinic's instructions about feeding before arrival; there is no single fasting rule for every cat or possible cause.
Update the clinic even after one bite
One small taste does not prove normal appetite has returned. Tell the clinic about any change and follow the recommended examination, monitoring or recheck plan. Meaningful recovery includes sustained food intake and ordinary behaviour, not only interest in a favourite treat.

Questions cat people ask
How long can a cat safely go without eating?+
There is no safe universal waiting period. Cats can develop serious complications, and the cause may already need treatment; contact a veterinarian the same day when meaningful food refusal persists.
Is it urgent if my cat wants food but walks away?+
Yes, that pattern can accompany nausea, mouth pain or difficulty swallowing. Drooling, vomiting, weakness, breathing change, possible toxin exposure or complete refusal increases urgency.

One isolated vomiting episode may be brief, but repeated vomiting is not normal. Count every episode and assess the whole cat—appetite, energy, pain, hydration and possible toxin or foreign-object exposure determine how quickly veterinary care is needed.
