Cat symptom guide: Not eating — the quick answer
✓ Treat this as urgent
✓ Call the same day, urgently if there are other symptoms or the cat is very young.
✓ Record timing, frequency and related changes
A symptom is information, not a diagnosis. Cats should not be left to go without food, and sudden refusal can signal pain or illness. When in doubt, a veterinary professional can triage the situation using your cat's age, history and current signs.
What this sign can look like
Cats should not be left to go without food, and sudden refusal can signal pain or illness.
What to do now
Call the same day, urgently if there are other symptoms or the cat is very young.
Useful information for the clinic
Note when it began, frequency, appetite, drinking, litter use, medication and possible exposures. Take a short video only if it is safe and does not delay care.
Why food refusal matters in cats
Dental pain, nausea, fever, stress, obstruction and many other problems can reduce appetite. Cats can develop serious complications after inadequate intake, and overweight cats are not protected. Young kittens and cats with diabetes or another illness may need even faster assessment.
What you can check before calling
Confirm when a normal amount was last eaten, whether treats are also refused and whether the cat can smell or pick up food. Note vomiting, stool, urine, breathing and possible access to hazards. Offer familiar food in a quiet place, but do not force-feed or repeatedly switch foods while delaying the call.
