sas is right. I once had a cat with kitty acne and I thought she was just old (she was!). But when our new kitten developed it also, I mentioned this to the vet and was warned about plastic bowls. (We were using inexpensive plastic bowls for water). Sure enough, I stopped using the plastic and the acne went away and the fur grew back on both of their chins.


My current crop of kitties now get their dry food in a plastic tower feeder, and their water in stainless steel bowls, and none of them have ever had kitty acne.
