Acne In Cats: Edit* Picture included

I was just going to post about this and I stumbled upon this thread - I was wondering about it b/c our Vincent has a touch of acne on his chin. I am not sure what we'll use, but we need to try something. Vincent just has little black marks from the acne - no scabs and all of his hair is there under his chin. I can definitely sympathize with him on the blemishes, as they bother me all the time!

I know they say glass and metal bowls are better than plastic, but he had the kitty acne coming into our house before he ever ate out of the plastic bowl we have. The reason we love our bowl is that it has one of those reservoirs on it, so we're not constantly having to fill it up - we just shake more down when the bowl part gets empty. Does anyone know of any stainless steel or glass versions of pet bowls with reservoir tops on them like ours has?

None of our other kitties have had feline acne before.

If anyone has any ideas, I'd love to hear them...
