We recently took in a stray 6-9 month old cat. For the past couple of weeks she randomly has fits of growling in discomfort. An episode can happen anytime, I.e., during sleep, while grooming, or whenever. Sometimes she will defecate a small amount during an episode. The vet thinks it is colitis. The cat got steroid shot and we’ve been giving her probiotics and antibiotics for a week now. She doesn’t seem to be improving at this point. Has anyone experienced something like this?
