Hi. I just recently adopted an orphaned kitten. I brought him to the vet today and he told me he was healthy. Before the visit with the vet I was feeding him KMR milk. The vet told me my cat is 5 weeks old and that it is old enough to have some solid food mushed in with its KMR. I fed him KMR only two times before the visit and feed him KMR/solid food twice after. About an hour ago he pooed out liquid stool two or three times. Is that diarrhea? As I was cleaning the mess I noticed what looked like a small amount of blood in his stool. Should I be worried?
