The specific causes of feline acne are not known. Cats with weakened immune systems are more susceptible, but otherwise healthy male and female cats of all ages may be affected.

There are a number of factors that may contribute to the development of the disease, including poor grooming habits, abnormal sebum production, and stress.

Lesions vary in severity, but are typically mild. Itching and pain are uncommon unless there is a secondary bacterial infection present. Lesions usually initially present at about one year of age, and remain cyclic for the life of the cat. Pain and/or itching are not common unless there is a secondary bacterial skin infection.

Your veterinarian will determine whether or not treatment is required. This will depend upon the severity of the symptoms, and whether or not any secondary conditions exist.

Feline acne symptoms and signs — Acne in cats may include lesions on the chin and lower lip, as well as swelling of the chin and around the mouth. Your cat may display dark brown comedones or crusted reddish papules.

In more serious cases, there may be a secondary bacterial infection present. Signs of this may include edema (swelling) of the chin area, or drainage of the lesions. In these cases, antibiotics, both systemic (taken internally) and topical, may be prescribed.

Sometimes, bacterial skin infections may appear to be acne, but are not. Sometimes ringworm or yeast infections may be mistaken for acne as well.

Treatment of feline acne — Treatment is often not necessary, except in more severe cases. In fact, skin lesions can be made worse by overtreatment.

Your veterinarian may recommend topical therapy of some kind to help remove the comedones (blackheads). Depending upon the severity, more aggressive treatment may be recommended.

Excess skin may be removed from the lesion area to aid in cleaning, as well as the application of topical medications. In order to prevent infection and injury to your cat, only your veterinarian should perform this procedure.

Treatment may include the use of antiseptics, such as Listerine or alcohol. Antiseborrheic shampoos may help as well. Some of these contain salicylic acid, which is a common component of human acne treatment formulas.

As with acne in people, topical benzoyl peroxide solutions are often prescribed. These are available in small animal strength formulas, which is one-half that of the human preparation, in shampoo or gel form.

Never use preparations designed for humans on your cat unless instructed to do so by your veterinarian. Even the animal formula benzoyl peroxide treatments may be irritating to your cat’s skin when used repeatedly.

Cats with acne who have weakened immune systems may receive steroid therapy. Additional supplements, including off-label drugs, may be used as well.
