He is normally a really active cat, and really sweet. My mom walked in with him in her arms and said he was laying on the pillow on her bed drooling all over it. He seems really uncomfortable. I'm really worried about him, I don't have money at all to bring him to the vet, and he's really special to me. He has his mouth open, and sometimes walks away and starts coughing horribly. We tried to look in his mouth and he wouldn't let us. He's a little over a year old, short-haired, neutered and front de-clawed. please help, im so worried!
