When it rains it pours!

I don't have a lot of advice but Tilly is my zitty kitty. She has chin acne.

The vet actually gave her prednisone.. I have her one for 3days and that cleared up the worst of it.

The peroxide and hot compress idea also is good. My vet said not to use neosporin because it will get licked off and might not be good for a kitty to injest.

My vet also gave me a sample of a special acne soap (and I STILL have most of it.. a tiny dab works great) and when Tilly has a zit attack I use that if it's a bit more bad than usual. The soap has hydrogen peroxide in it.

Good luck with it!
