Cats have small sebaceous glands associated with hair follicles and larger sebaceous glands on the head and tail. These glands secrete oils. It is when these glands are overactive that cats can get what is known as cat acne.
In cases of acne the pores and hair follicles near the glands can become clogged with black sebaceous material, and form what is known as comedones. In the more severe cases these pores and follicles can get infected, irritated, and swollen. Cat acne is most commonly seen on the chin and this acne will look like the cat has black dirt on the chin that won't wash off. Symptoms may include red swollen pores or black clogged pores.

Some cats seem to get acne in conjunction with an allergic reaction to plastic food bowls. If you suspect this you may want to switch to metallic bowls and see if that clears the acne up.

I recommend changing to a completely raw diet if not already and swap to non plastic food & water bowl.

Rub on the acne Castor oil once daily which will stimulate the clogged pores to pop! Leave on for 12 hours. Then wash the area with a combination of cool chamomile tea, organic cider vinegar & colloidal silver in equal amounts. All these products are available at the health food store. The castor oil can be obtained from your chemist.

Castor oil is a purgative so don't slap on a large amount just a little bit & rub in well.

If this does not clear the problem then the condition can be treated with the blood cleanser & topically an Antiseptic Styptic.
