My cat has IBD symptoms like pain, but no diarrhea. Is it peritonitis?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered

My 2 yr old male cat has been diagnosed with IBD. He had vomiting and was losing weight and the stopped eating. He had severe abdominal pain. However he did not have diarrhoea at any time. Everything I've read suggests he should. I have researched peritonitis and it fits more with that. Particularly curling in a ball protecting stomach and whining.

Many cats with IBD do not have diarrhea, so this doesn't necessarily mean that the diagnosis is wrong :) But if you're concerned and Wilson isn't improving with his current treatment, I would definitely recommend calling your veterinarian or taking him back in for a recheck. It sounds like he may need some additional testing to help figure out why he isn't getting better, as well as some changes to his current treatment plan.
