Hi, I joined this forum to try and get some feedback from other owners. My cat, Ernie, has a skin condition that my vet can't seem to nail down. He his overly dry, red and irritated. There are dark brown patches all over him, especially in between his toes. He is obviously uncomfortable. My vet gave me a cortizone shampoo to use, and said to moisturize him afterwards. This Doesn't really help. Anyone else come across this?
