Question

Belly
I rescued a male cat several years ago. The vet currently estimates his age to be around 9. When he was rescued, he was missing much of his fur. Once taken in and fed a proper diet, his fur grew back, but he had a habit of ripping his own fur out (mostly his stomach and back). Several trips to the vet confirmed allergies, but not the type. He was originally started on the over-the-counter allergy medicine which did not help. He received cortisone injections, but became diabetic (he is now in remission). His food was changed to a grain free diet, bought special food from the vet, tried a raw diet, cooked the food myself, all to no avail. We tried cyclosporine but it didn't help at all. The vet feels we've done all we can do and has referred us to a dermatologist for allergy testing, but we were informed this isn't an exact science. I know he's uncomfortable and he's chewing himself to the point of bleeding. I am planning on taking him to the dermatologist as soon as I can afford it. Is there anything I've missed or anything I can do to make him more comfortable?

Answer
Some of these refractory cats actually have ringworm or skin parasites, like mange.  The steroids will only make that worse.  If your vet can prescribe sporanox or fluconazole, that may help in 2-3 weeks while you are waiting to go to a dermatologist. A treatment with ivermectin or a dipping in lym-sulfur may help.
