My old cat won't eat for days. What can I do to make her eat?

Updated On September 23rd, 2025

Pet's info: Cat | British Shorthair | Female | spayed | 5 lbs

Hi following up on my previous question - she has had an appetite stimulant and still isn't interested in food. my main worry right now is getting her to eat as its been 4 days with no food now and my vet says he thinks we should put her to sleep if she doesn't eat by Friday! The only thing I've managed to get her to eat is an egg yolk. Sadly the radioiodine therapy is too expensive and she is 15 years old. Sorry I just hate seeing her so thin as she must be suffering - so need her to eat!

I understand what you are saying. Unfortunately, if you have run blood tests and there is no evidence of kidney or liver disease, no evidence of any significant infectious disease, or any sort of electrolyte balance, the most likely cause for an extended period of inappetence and weight loss in an elderly cat is cancer. Specifically, the cancer is usually gastrointestinal lymphoma. X-rays and ultrasound would help in trying to confirm or rule out this diagnosis, but this is an all too common and unfortunate end to many kitties. I would continue to try and just feed her anything that she wants. Literally anything if it gets her eating is fine. I hope you and Suki can figure things out.
