Violet, the SD is dry (I have only ever fed him dry food), and I really don't think it makes much difference, but he was eating natural food before, so it was pretty healthy, just not specifically hypo-allergenic.
Sorry to threadjack but I am so glad to have encountered others battling this problem! My cat has been battling with EGC on his lips/mouth to the point that his nose is half gone and he has lost several teeth. He is 5, but this has only been a problem over the last 2 years. Depo shots work...
