When we took our Diva in for such an odd malady the vet said it was cat acne. Having owned pets all my live, I was floored. I never heard of it. He told us to keep her clean but she really didn't like it. Just to do something that might help, I used baby wipes. It went away quickly. I'm not sure it matters what you clean with, just that you do. It could be that Diva is just special that way.
