My kitten has bloody stool after neuter, but acts normal. Vet ER?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered

Hi there, we have a 3.5 mo old kitten. He was neutered on Thursday. Today he had a stool that was light brown, very soft, with streaks of mucous and blood. He's behaving totally normally- playing like his usual self. What should we do? Should we take him to a vet ER tomorrow (most vets are closed on sundays)? Or should we wait until Monday for a regular vet appointment?

I'm sorry Tuck isn't doing well! Given that he's otherwise behaving totally normal, it should be fine to wait until Monday. Certain medications can cause blood in the stool, and if he's on any medications from the neuter, that could be the cause. It could also be that he has intestinal worms causing the blood. I would keep a close eye on his tomorrow, and if he starts becoming lethargic, the amount of blood in his stool increases, he stops eating, he vomits food, stops drinking, and/or vomits water, then yes I would take him into a vet ER. I hope this helps!
