Unfortunately, blackheads and acne are not just for teenagers—they can turn up on your cat’s chin, too, as they have on Chiggy and Caymus. Tap the link below to see videos on this post to see what I mean.
The main result is an excessive production of sebum. This is an oily compound normally produced in the skin to protect it from various environmental factors, but in the area affected by dermatitis, the sebum production greatly outweighs the normal amount.
Exposure to plastic—plastic feeding bowls or other plastic around the house. If your cat has a sensitivity to plastic, then it may develop chin acne due to the repeated contact of that area and its bowls.
Stress – The link between stress and dermatological issues in cats is well-known. If your cat is going through a particularly stressful period, then it might develop dermatological issues and chin acne is one of the many possibilities.
