We are taking the jacket off a couple times a week to let the skin air out and so that she can clean herself naturally, but this one spot is horrendous. There is some hydrocortisone on the area, and she was licking herself as I was snappjng these.
My cat had a similar looking condition on his head and the vet gave us some antibacterial wipes for the area I believe you can get them at the pet store, I'll check what they're called when I get off work
