Last night I noticed Popsie had diarrhea in his litter box. I thought I might have given him too much enulose yesterday because I was worried he wasn't eating what I'd put in his food. Today when I got up there were little spots of poo all over the house. They are black too which worries me. I also think I saw a bit of vomit. I'm wondering if it's the special food giving him the runs.
