So, about a month ago I asked for some help with my male F4 Savannah. We adopted him November 19, and since has had terrible diarrhea. I've bought purina hard food for sensitive stomach, he's been to the vet twice. Once he tested positive for Coccydia (spell?) and received a weeks worth of liquid antibiotics. No use, so he went back and this time the vet thought it could be feline IBS so he prescribed a broad spectrum pill antibiotic to get rid of any possible remaining parasites and a weeks worth of steroid pills. It helped Simba (the 5 year old male F4) to use his litter box more (he always uses it to urinate, but has several severe diarrhea accidents throughout the day) but it did not clear up the diarrhea, just seemed to allow him to better control his bowels. He is drinking water fine and playing fine, he just keeps having severe diarrhea and accidents all day every day. Does anyone have any experience with this? He will be going BACK to the vet this week to see what the vet recommends but for now, any suggestions?
