Our cat hasn't eaten in four days, I took him to the vet yesterday and he had extensive bloodwork. Some of his counts were low, but the vet didn't seem to concerned, and one was really low and the vet couldn't figure out why. He prescribed Clindamycin and Metacam, and said if he hasn't eaten by Monday to call back. Last night Spencer started with really bad diarrhea and projectile vomiting. He still isn't eating, and is still vomiting. I stopped all meds, but am wondering if I should still give the Metacam, because he is hiding and just lays there, which could be because of possible pain? My vet isn't there on weekends, and I'm not sure if I should start the pain med again. Hes drinking water well, but won't eat anything, and I've tried everything.
