1
Take your cat to the vet if they have swollen pimples or open wounds. Feline acne usually looks like small black dots or dirt. If the blemishes swell up or look red and inflamed, it may mean there’s a sign of infection or bacteria. To be on the safe side, set up a vet appointment to make sure your cat doesn’t get sick or have any other conditions.^{[9]

Research source}
- Cat acne is pretty common, so there’s no need to be concerned if you see fewer than 20 small black spots. They might not even bother your cat and could disappear on their own.
2
Have your vet take a skin sample to rule out other infections. Your vet will scrape a small sample from your cat’s skin to run tests. That way, they can make sure your cat isn’t suffering from a different skin condition with similar symptoms.^{[10]

Research source}
- Your vet may also check the sample for mites, bacteria, or fungi as well.
3
Give your cat antibiotics if your vet prescribes them. Your vet will either prescribe a topical or oral medication if your cat has a severe case of acne. To give your cat oral medication, either use a medicine dropper or mix it with their next meal. If you’re using a topical medication, rub it onto your cat’s acne so it absorbs into their skin.^{[11]

- You’ll usually have to give your cat antibiotics for 4–6 weeks.
- Your cat may need to take steroids to reduce inflammation in severe cases of feline acne.

- Cat acne can also form around your cat’s upper lip.
- Small blackheads could swell into larger pimples. If your cat scratches at them, you might notice small scabs or a rough texture on your cat’s chin.
- If your cat has acne around the base of their tail, then treat them for “stud tail.”

- Wash the dishes every day with soapy water to keep them clean and bacteria-free.

Change your cat’s diet if you suspect food allergies. Talk to your vet and ask them about what cat food would work best for your cat. When you transition your cat to a new diet, offer them the old and new food at mealtimes. When your cat starts eating the new food regularly, wean them off of their old food by about 1 tablespoon per day.^{[22]

- Watch your cat’s acne while you’re switching food. If their acne seems to get worse, go back to their old diet and consult your vet.

Create a calm stress-free environment for your cat at home. Cats can be sensitive to stress and changes around them, but you can do a lot to help them relax. Make a comfortable space for your cat with their bed and some toys so they have a safe spot to hide. Pet your cat and give them some attention every day to create a daily routine.^{[23]

- Try to avoid making loud noises and having lots of people over since all the commotion can stress your cat.
- If your cat still acts stressed out, talk to your vet to see if they can prescribe a calming medication.

Using hydrogen peroxide on a cotton ball to scrub the affected skin will help remove the lesions (which are caused by a buildup of oils). You should be gentle with hydrogen peroxide though, and consider talking to a vet.

Expert Answer

The key to preventing feline acne or reducing the severity of a flare up is cleanliness. Any gentle cleaning solution when used regularly will help. Diluted salt water or diluted chlorhexidine are good options. Apple cider vinegar will have a mild astringent effect, so there is a risk of drying out the skin, but when used diluted, this should be minimal and the cleansing effect beneficial.
