Is my pet sick and not eating due to neuter surgery complications?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 5 months and 5 days old | 4.2 lbs

Watson was neutered and vaccinated when he was about five months, but only three pounds, by his rescue group. He's pretty skeletal right now, and is having a hard time eating and drinking. Could the surgery have made him sick - well, sicker? I'm waiting on his bloodwork results from his vet.

It isn't likely to have caused whatever is causing the symptoms. It is likely he had a pre-existing condition that may have been aggravated by the anesthesia. Many of these drugs are filtered by the liver and kidneys. Blood work is a start. Submit a stool sample to diagnose intestinal parasites, bacterial overgrowth or malabsorption/maldigestion issues. Whatever the underlying cause, supportive care is likely indicated. Discuss a feeding tube and parenteral nutrition (IV nutritional support) with your veterinarian.
