My poor Bronco is dealing with a bad case of feline acne. One vet suggested using plain Listerine on it. Another vet suggested Stridex pads that have a main ingredient of benzoyl peroxide. They no longer make those however and all of them have a main ingredient of salicylic acid. Nothing seems to be working. He eats out of clean stainless steel bowls every day. I give him limited ingredient diet food as well because he already has food allergies. I'm at such a loss at this point. I think it may be time for yet another vet visit and inquirie about antibiotics. You can see it in the picture where he's looking up Vader. It's hard to get a closer picture because he's such a wiggle butt!
