I've recently discovered a white bump, about the size of a tack head, on my cat's belly near her teat. There are also brown spots around the bump. She's not sick, and she isn't bothered by me touching the area. Does anyone know what this might be?

Is she an indoor/outdoor kitty? Is she on Flea preventative? Could be nromal pigment changes as far as the brown stuff. Is it flaky or in the skin? If I had to guess without looking, I might venture out to say it is an abscess. No matter what I think, run her by her vet and they can take a look-if it IS an abscess, sooner rather than later is the ticket!
