He's also developed Cat Acne on his upper lip. At first we thought the white was changing colour and for a couple of days we made a joke that he was developing a Hitler stache. But after closer observation, there were tiny black bumps on the skin. My cats had this growing up, but it usually developed under their chin. After some research, I found the cause could be plastic food and water bowls, which is what they had. I changed their dishes to stainless steel and the acne cleared up completely.
