It started about two months ago with an awful light brown horrible smelling diarrhea from two cats. Now it has hit everyone in the colony of 50 cats. It seems to stop and start, I really don't know what to do. Is there a colony caretaker here who has gone through this? If so, what was the solution? I realize I could take one to the vet, to determine what it is and what medication is needed, but then how will I medicate all 50? I started trying to save a little money this year by feeding 2 or 3 cats from one paper plate rather than individual paper containers for each cat. I am guessing that is what has caused the problem, but I can't be sure. At wit's end. Any ideas or suggestions would be so appreciated! Thanks in advance. Sally
