My uncle found an abandoned kitten outside their house. It was less than a week old. I took him in and since Kitten Milk Replacement Formula is not available in my area, I started giving him goat milk instead. About 5 days into feeding him goat milk he started to get diarrhea. I ordered Royal Canine Kitten Milk online and started feeding that instead. Now, his diarrhea has stopped but this morning he had really grey-ish clay like poop. Does anyone know why this might be happening?
