This cat(Charlie) was rescued with an animal bite on his right side of his head. He has been vomitting for over a month. He has lost a lot of weight(see picture before he got sick, 14 pounds, now under 7pds, he lost all muscle mass). He is lethargic. The vet put him on Amoxicillin, and anti-vomitting medication. It didn't help with his vomitting. We took him to another vet. This vet put him on prednisone, Raglan, and pepsid. He has been taking prednisone for 7 days. It doesn't help. He doesn't drink and eat himself. We have to hand feed him. He throws it up right after he eats. He had CBC(complete blood cout) and urinanalysis. They all turned out normal. He has no diarrhia. His stool is tiny and dark. His vomitting stuff is white sticky stuff with food. When he vomits, he grinds his teeth hard, gagging and retching. He looks awful. He has lots of dandruff. He doesn't move around but lying in his bed all the time. We are desperate to get help for this little guy!! Please help!
