Cat's skin is irritated, vet is usless! any ideas?

Try this stuff..it is pretty good and worked great for my dog. Virbac anti itch spray for dogs cats and horses. They were bought out so the brand name may have changed but this is it. thanks a href="http://www.petmedstore.com/Merchant2/merchant.mvc?page=petmedstore/PROD/VibRelAntiItchSpray" rel="nofollow"http://www.petmedstore.com/Merchant2/mer…/a
