My cat stopped eating after neuter surgery for days. Is it serious?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 1 year and 8 months old | 11 lbs

Kovu got neutered a week ago today, and ever since the surgery he has gone from eating 3 cans of wet food and a whole bowl of dry food in a day, to 1/4 can of wet food only in a day. Now for the past 3 days he wont eat at all. he doesnt seem to be in much pain, but he refuses anything i give him. i cant get ahold of his vet. what can i do? as a kitten he went through a time where he stopped eating and went from 11 lbs to 4 lbs, but got his weight back up and hes about 9 lbs now. im worried.

That is concerning that Kovu has suddenly stopped eating as much and has not eaten for the past three days. That makes it a medical emergency. When a cat doesn't eat for three days, they will develop a fatty liver which is fatal without treatment. Since you cannot reach your vet, you need to take him into an ER vet clinic now or find another vet in town to see you. Best of luck.
