I noticed my cat was losing fur around his face about a month and half ago. He was also very lathergic, just not himself I took him to the vet who said it was probably allergies, gave him a shot and two weeks worth of pills and said it should do the trick. It seemed to be working but as soon as the pills ran out, it started again. So I went back to get more pills. Well he seems to be feeling back to normal again, but the hair loss is getting worse. On the top of his head, around his face and now the small of his back. There are also small red spots on the skin. Does anyone know what is causing this?
