What causes feline acne?
The exact cause is not always clear. Abnormal keratinization, oil production, grooming, local irritation, stress, and secondary bacterial infection may contribute. Plastic bowls are sometimes suspected because scratches can harbor debris, but switching bowls is not a cure for every cat.
What does it look like?
Mild disease often appears as pepper-like black comedones. More advanced lesions can include redness, swelling, pustules, crusts, hair loss, or draining infection.
How is it treated?
Treatment depends on severity and may include gentle cleansing, topical veterinary antiseptics, treatment of secondary infection, and investigation for mites or fungal disease when the appearance is atypical.
What should I avoid?
Do not use acne products made for people, essential oils, concentrated peroxide, or aggressive scrubbing. These can irritate feline skin or be unsafe if licked.
