On Monday my boyfriend and I just bought and moved into our new house.. so we went and rescued our new kitty from one of our local shelters. He looked completely fine at the shelter, and nothing came up at the vet. No health conditions came up on any of his papers. He was playful and loving and wanted to be around everyone. But after a day or so he started hacking and gagging. We thought that he might be allergic to his cat food, so bought him wet cat food in a different brand. But he's still doing it, and now it's getting worse. Now he's throwing up foam/food multiple times a day. He can't keep his food down at all. He's reverse sneezing, and breathing through his mouth. His nose is still wet. He's a short hair cat, but he does shed a lot. I have a brush that I brush him with. All he wants to do now is lay down and hide. He's not really interested in anything. And when he gets up and moves, most of the time he'll start hacking again. We got him some hairball remedy gel and he wasn't interested in it. Kinda had to make him eat it
