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.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is possibly due to allergies. A secondary infection is likely and also needs to be addressed. Those pimple like lesions could be from scratching perhaps. There are many things that can cause allergies though in most cases they can be broken down into 3 big categories: flea, food and environmental allergies. Allergies are usually worked up in a stepwise fashion starting with flea allergies as this is the easiest and cheapest to take care of. If not on a flea preventative, then it would be a good idea to get started on one. If already on one then it would be a good idea to change to something else (there are many new products out in the market). If not improved in 1-3 months then it is time to move on and check for food allergies by switching to a novel diet (new protein and new carbohydrate). If that does not seem to be the issue then you are left out having to check for environmental allergies which require blood and/or skin tests. Allergies can be very frustrating to deal with at first but so rewarding at the end when we are able to treat them effectively!
