Does anyone have any advice? Last night my cat slept ALOT, I knew he didn't feel good. Tonight he has diarreah and is miserable and meowing. He ate dinner though, tuna in a can (well half of it). The day before though he ate Friskies, and I was wondering if he got some sort of food poisoning, or is it a cold...what can I do for him? I didn't want to take him to the vet.
