I brought Nimbus home on August 5th, 2011. He is a neutered Ragdoll born on 4/30/2011. When I brought him home he had a had a big belly. I figured it was just a Ragdoll thing since they tend to be heavier set cats. Since I've gotten him, he has had intermittent loose stool/diarrhea. At first I thought it was the can food I was feeding him that was causing it but after taking him off it, he continued to have intermittent loose stool. I work at the NC State Vet School and took Nimbus to the Wellness Center last Friday. The doctor felt his belly and said that it wasn't that he is "chunky" but that his belly is distended. Now we are looking at a number of possibilities. I'm aware of FIP and that it is fatal. I also know the difference between wet and dry FIP and that a distended belly can possibly mean wet FIP. However other than the intermittent diarrhea, Nimbus is not showing any other symptoms of FIP. He is acting completely normal. He runs around and plays. He has an excellent appetite and he drinks plenty of water. If it were effusive FIP I would think by now he would be showing more serious signs of sickness such as fever, trouble breathing, etc. since sources I've read have said that effusive FIP manifests somewhat rapidly (but then I know there are exceptions...however he has had this distended belly for at least a month now). Another possibility the doctor is thinking of is Tritrichomonas. We had a PCR test sent off and are waiting on the results. All of his symptoms fit what I've read about Tritric except the distended belly. He has intermittent diarrhea and the consistency of it is cowpie-like. The stool has a very fowl odor and he is occasionally gassy. Anyone have any experience with Tritrichomonas? Or perhaps other ideas of what could be going on?
