Onyx has been going bald for a while. We took him to our vet in CA and he said it was most likely an allergic reaction to fleas. So we put him on flea medication and he is getting worse. His back legs are bald, and now his armpits are going bald and hair thinning. He has an appointment at a new feline vet for Monday. I have looked at the identifying skin disorders and nothing really seems like what he has except Feline Endocrine Alopecia, but I don't think he really has that. He doesn't have any red sores, just hair loss, where it is bald he has little curly short gray coarse hairs. I have felt a couple scab like things on his back thighs, pea size. Any idea what this could be and what tests I should get run on him?
