Feline acne shows up as black dots and small bumps on the chin and lower lip — clogged hair follicles that can progress to red, painful, draining infections in some cats. It is most often triggered by plastic food bowls, oily chin glands, and poor self-grooming. Switching to stainless steel or ceramic bowls and gentle daily chin cleaning resolves about 70 percent of mild cases (Jazic et al., 2006, Vet Dermatology).

What Feline Acne Actually Is
Feline acne is a chronic disorder of the sebaceous (oil) glands and hair follicles on the chin and lower lip. The follicles become plugged with oil and dead skin cells (the black dots are called comedones, the same as human blackheads), and in some cats this mild plugging escalates to inflamed, red, painful, often-infected lesions with pus or scabbing. It can occur at any age and in both sexes. It is not the same as ringworm, eosinophilic ulcer, or food allergy, though all three can look similar at first glance.
What Owners See First
The earliest sign is a smattering of small black specks on the chin — many owners initially think it is dirt or flea dirt. With a fine-tooth comb the black material does not flake off easily because it is embedded in follicles. Over time some cats develop small red bumps, scabby raised lesions, and a thickened, swollen chin. Severely affected cats can develop draining wounds and significant pain. White and short-haired cats often show the discoloration most obviously. Some cats are itchy and rub or scratch the chin against furniture; others ignore it entirely.
Why Plastic Bowls Get Blamed
Plastic food and water bowls are by far the most commonly identified trigger. Plastic harbors bacteria in tiny surface scratches, can leach chemicals that irritate skin, and rubs against the chin during eating in a way that traumatizes already-oily follicles. The WSAVA Global Nutrition Guidelines, 2011 emphasize that food-bowl hygiene affects skin and oral health, and ceramic or stainless-steel bowls washed daily are a simple high-yield change in mild acne. Removing plastic bowls alone resolves a meaningful proportion of mild cases.
How Vets Approach Treatment
Mild cases: clean the chin daily with a gentle warm wet washcloth or a chlorhexidine-based wipe (designed for pets), switch to stainless or ceramic food and water bowls washed every day, and recheck in 4 to 6 weeks. Moderate cases: add a topical antibiotic gel (often mupirocin) or a topical benzoyl peroxide product designed for pets twice daily for 2 to 4 weeks. Severe cases with deep infection: skin cytology to identify bacteria or yeast, sometimes a culture, and a 3 to 6 week course of systemic antibiotics chosen based on culture. Pain control follows the AAHA Pain Management Guidelines, 2022; severe lesions are uncomfortable and short courses of NSAIDs or buprenorphine may be appropriate.
What Owners Should Not Do
Do not pop or squeeze the comedones — this tears follicles open and turns mild acne into deeper infection within hours. Do not use human acne products like high-concentration benzoyl peroxide or salicylic acid; both can be toxic to cats at human-product concentrations. Do not use rubbing alcohol or hydrogen peroxide on the chin — both delay healing and cause pain. Do not assume long-haired cats are immune — they are not, they just hide the lesions until the chin is thickened and tender.
When to See a Vet
Call your vet today if:
- A swollen, red, or warm chin in a cat
- Visible pus, scabs, or drainage from chin lesions
- Pain when the chin is touched, or pawing at the chin
- A mild case that has not improved with bowl change and cleaning after 4 to 6 weeks
- Recurrent acne in a cat with other skin problems (whole-body itch, hair loss elsewhere)
Go to the ER immediately if:
- A severely swollen face or jaw that is interfering with eating
- A cat who suddenly cannot open the mouth or stops eating entirely
- High fever with severe lethargy and refusal to drink
- Heavy bleeding from a chin lesion that will not stop
- Sudden facial asymmetry or unilateral swelling that wasn't there yesterday

Frequently Asked Questions
How much does feline acne treatment cost?
For mild cases, the cost is essentially the price of new stainless or ceramic bowls (around $10 to $30) plus a tube of pet-safe wipes (about $15). For moderate cases, a vet visit, cytology, and a 2-week topical antibiotic gel typically run $150 to $350. Severe cases needing culture, a 3 to 6 week course of systemic antibiotics, and rechecks usually total $400 to $900. Recurrent or refractory acne sent to a dermatology specialist may add $300 to $600 for the consult plus advanced diagnostics.
Can feline acne be cured?
It can usually be controlled but rarely "cured" permanently. Some cats outgrow it; others have lifelong tendency and need routine chin cleaning, ceramic bowls, and occasional flare treatment. The goal of management is to keep the chin smooth and comfortable, prevent the deeper infected lesions, and minimize cosmetic changes. Daily home maintenance is the single biggest factor in long-term control.
Is feline acne contagious to other cats or to people?
The base condition is not contagious — it is a follicular plugging issue specific to the affected cat. The secondary bacterial infections (staph, sometimes Pasteurella) are theoretically transmissible but rarely cause problems in healthy household contacts. Standard handwashing after treating the chin is enough.
My cat's chin is bald — is that just acne?
Sometimes, but bald patches on the chin can also be from ringworm (especially in young or immunocompromised cats), from a yeast overgrowth, or from eosinophilic granuloma complex. A vet visit with skin cytology and a Wood's lamp or dermatophyte culture sorts these out quickly. Do not assume bald spots are "just acne" without an exam.
How often should I clean my cat's chin?
For active mild acne, gentle warm-water cleaning once or twice daily for 2 to 4 weeks usually clears the comedones. Once the chin is clear, 2 to 3 times weekly maintenance is enough in most cats. Use a soft cloth or pet-safe wipe — never scrub. If the chin worsens after cleaning, stop and ask your vet whether the wipe ingredients (chlorhexidine, mupirocin) are right for the lesions you are seeing.
