Feline acne may affect both male and female cats of all ages. The specific causes of the disease are not known. Cats with weakened immune systems are more susceptible.
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 usually initially present at about 1 year of age, and remain cyclic for the life of the cat. Lesions are typically mild, but secondary bacterial skin infections may cause pain or itching.
Depending upon the severity of the symptoms, and whether or not any secondary conditions exist, treatment may or may not be required. Your veterinarian will have to make this determination.
Feline acne signs and symptoms — The clinical signs of acne in cats may include lesions on the lower lip and chin. Your cat may have dark brown comedones or crusted reddish papules. In addition, there may be swelling of the chin and around the lips.
Secondary bacterial infections may be present, involving swelling of the chin area, or drainage of the lesions. In these cases, both systemic and topical antibiotics may be prescribed.
It’s possible to mistake bacterial skin infections for acne, but appearances may be deceiving. 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.
Topical therapy of some kind may be prescribed to help treat the comedones (blackheads). Depending upon the severity, more aggressive treatment may be recommended.
Your vet may remove excess skin from the lesion area. This facilitates cleaning of the area, as well as the application of topical medications. You should never do this yourself as you can hurt your cat or cause an infection.
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.
It may be effective to use topical benzoyl peroxide solutions in gel or shampoo form. Benzoyl peroxide preparations made for small animals are half the strength of those made for humans.
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.
Immune compromised cats, such as those suffering from feline AIDS may receive steroid therapy treatment for feline acne. Additional supplements may be used as well, including off-label drugs.
