Why does my cat have pimples, sores, and hair loss on her chin?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 8 lbs

My cat has sores in a small area under her bottom lip. They are sometimes puss filled or just lumps with a black head. They look like pimples for the most part. Hair loss in that area. Otherwise she seems normal and no difference in her.

This is probably caused by an allergic reaction. first of all make sure you de-flea Pixie regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or cyclosporin in order to stop the allergy.
