My kitty is 8 months old and has been having loose stools and diarrhea at times. He is not lethargic or appears to be sick. No fever or anything. He has a great appetite. I feed him wet food (Purely Fancy Feast -new formula) which he loves and friskies dry food. I have not noticed any blood in his stool. There are no worms or parasites around his anus that I have noticed. He has a vet appointment this Friday, but does anyone have any input on what the culprit could be or am I just being a nervous nelly. This is my first kitty! Thanks in advance.
