Acne on Your Cats Chin
Cat food contains oils that cling to plastic bowls. As it creates a buildup it can and will clog the hair follicles on your cat's (yes, or dog's) chin. The result is the acne or pimples that can become infected. You can clear up any blackheads -- the first sign of acne -- by wiping your cat's chin with hydrogen peroxide a few times a week. If the acne persists, have a vet check for other conditions.
Removing all
plastic bowls and switching to scratch-resistant glass,
metal, or ceramic can help your cats be acne-free.
