I'm a little concerned about my 8 week old tabby kitten. We only got her today and she has already passed tow diarrohea stool, the last of which I noticed there was a slight sign of blood loss. Not a lot, but enough to colour a few of the cat litter stones. She's lively and playful, hasn't yet eaten or drank anything since we bought her home. Should I seek advice from the vet?:confused:
