Feline acne starts as comedones on the chin and lower lip. Poor grooming may be a factor. Stressed cats may just hunker down and neglect their personal needs. When a cat doesn’t rub his chin naturally, dead skin cells can plug the hair follicles. The upshot can be inflammation and infection. An accurate diagnosis should start with a bacterial culture. In addition to a carefully chosen oral antibiotic cats with chin acne will need a benzoyl peroxide gel like Oxydex. I hope you’ve found this information on cats helpful. And I hope you’ll share it with your cat loving friends. If they check their kitty’s chins and find lumpy bumpies, or black heads, they’ll be glad to have this information.
