I've had my cat for a few months now. I found him outside with an injured leg. He has been to the vet and they said he was negative on Felv, and Feline Aids. We didn't get his shots because we didn't plan on keeping him this long. He is inside only now. I have 3 other cats who all do have their vaccinations. He is a very shy cat and hides under the bed. He doesn't like people at all except when I bring him food he will rub up against me. The problem is for the past week or so he has had diarrhea. I can't tell if its bloody or not. It's kindof like pancake batter I guess. I with held food from him for 24 hrs, and tried to feed him rice after the 24 hrs.. he didn't like the rice and I didn't want to make him go hungry so I went back to the food. He has had diarrhea all throughout this time. It's all over his rear end. We are taking him to the vet Friday to get him checked out.. I was just hoping that someone could provide me with information.. or possible causes?
