Our tuxedo cat Gumby is FIV+. It may be due to his condition that he suffers from terrible allergies that used to leave his skin in pretty bad shape. When we first had him as our foster kitty, he had bumps on his skin at the base of his tail and at his haunches. We could see he was in misery from the itching -- it was awful. It was recommended we ask the vet for a steroid shot to help relieve the itching. This did wonders for his comfort, but we still had to get to the bottom of the skin issues.Something else that helps with skin irritations and allergies is this topical hydrocortisone spray from Excel.
