Okay, I know that a number of Pet Talkers have some experience with this. Could it be pancreatitis? I really think it is an abdominal related issue. I know that doctors have pressed and pushed and he hasn't reacted. But he isn't eating or drinking, and he stands hunched over and shakes. I took a look online and it looks like it should have shown up in his blood tests, and it didn't. I don't know if that means it definitely cannot be that. Also I have been doing everything possible to make him eat, but maybe I shouldn't do that and see if he feels better. I don't know. I am still trying to find ways to make him feel better. Thanks for listening fellow PTers.
