Can someone PLEASE tell me if they know or have had done a test to determine whether their cats skin issues where food or environmental? I'm going back again to the vet tmrw. And I guess I have no choice at this point but to try the Atopica (I pray it helps) but I truly believe my Cream's skin issues is environmental. Bc my other 3 have itchy skin, ears, licking groin area. Just they r older n have healthier immune systems bc it has not effected them like Cream. Btw - they don't eat the same food, they do NOT have fleas. I always wondered if it was the liter.... Or all the toys, scratchers, cat trees, all made in China. How do we know what these materials really are. I've had animals my entire life and I'm 46 and I've never heard of so many skin issues with skin like this.
