Pet's info: Cat | Siamese | Female | spayed | 11 years and 7 months old | 13 lbs
Cat has a pinkish bump on her back. Thought it was a skin tag about 6 months ago but it looks bigger today and has some white kind of chunky pus coming out now

Hello. This is probably a sebaceous cyst. Do not squeeze on it, but do clean it gently with a skin antiseptic like Hibiclens ( available at all pharmacies ). You might want to have your vet take a look just to make sure, as we can see other lesions that look similar. Thanks for using Petco Pet Education Center, formerly Petcoach.
