How Long Can a Cat Go Without Eating or Drinking?

Last Updated on April 16, 2026 by admin

If your cat has stopped eating or drinking, treat it as a same-day veterinary issue. Cats can decline quickly when appetite loss is caused by pain, nausea, dehydration, or another illness.

What matters most

A short skipped meal is not the same as a fast, but a cat that refuses food for about 24 hours, or is clearly not drinking, should be checked by a veterinarian. Kittens, seniors, and cats with chronic disease need help even sooner.

What you can try at home

  • Offer fresh water in a clean bowl and place a second bowl away from the food area.
  • Try a fountain if your cat prefers running water.
  • Warm wet food slightly to improve smell.
  • Serve a familiar food in a quiet space and keep stress low.

Call the vet now if you see

Repeated vomiting, sunken eyes, drooling, hiding, trouble breathing, severe lethargy, or a cat that will not eat and will not drink. Do not try to wait this out.
