I have a 3 year old male cat with pretty severe skin issues, and I need advice on what to do next. Back in May, we discovered a UTI. We took him to the vet, and they, of course, switched to his food. He stayed on the vet's prescription food for a couple of months. Once he finished the bag, we switched to a new food, as suggested by the vet. I think it was September that we first noticed the scabs. My first thought was fleas and I immediately applied Revolution to both cats. By October, the scabs were getting worse, despite there being still no sign of fleas. We took him back to the vet. The vet also thought fleas but couldn't find any evidence of them. She gave him antibiotics and a steroid shot and told us to switch his food. She said it could take up to 3 months to clear up if the reaction was a food allergy. Towards the beginning of November, I began to get really worried about how much he was scratching. He was tearing his skin up, into bloody scabs and breaking his nails. We took him back, for a second round of antibiotics and a cone. The vet instructed me to give him Benadryl, but when attempting to do that ended up in new scars for me and barely any Benadryl in his mouth, they gave him a second steroid shot. And that's where we are now. He is still desperately trying to scratch. The cone helps, but the scabs are still there and he has severely broken at least one toenail. I don't know what to do. I can't tell if it's the food, because it's not getting better. I can't stand seeing him so miserable. I would very much appreciate any ideas on what to do next!
