Bit freaked out, 13week old kitten comes in the room and starts heaving and hes got some vile drool hanging out of his mouth with cat littler stuck to it. We get the cat litter off, but the 'drool' wont budge. OP goes into kitchen where he sees a massive slug on the floor (thought it was a cat poo at first, if only) with a trail coming from the litter tray. The cat then does a wee under the toilet, which he has never done (guess he wasn't to keen on going back in the litter tray). After some intense grroming he's got most of the gubbins from round his mouth and he seems fine. I didn't see the slug but OP says it was huge with some yellow spots. Cat seems fine now, acting normal. Was just odd. Sorry that was random.
