My cat, Meowgi, was given an anti inflammatory injection a week ago. A couple days later, he was not looking so good so we took him to another vet, where we were told that his red blood cell count was low. He said this may have been a side effect from the anti inflammatory. That night, they gave him steroids and anti biotics. By the next day, his red blood cell count was normal, no more anemia, but still a little of a fever. The vet gave us Clavamox for the infection-this was on Friday. For the next few days, he seemed sleepy, but ok. On Sunday, he looked like his normal self - eating a lot. Yesterday, however, he didn't really want to eat. He ate in the morning, but nothing after that. At 2 am this morning, Meowgi threw up! So, now I'm worried. He had been doing well on the Clavamox for a few days, and now this. Is this normal? Should I be worried? The vet opens at 9am, so I'm calling them as soon as they open...
