It wasnt infected like puss, it was just scabby sort of because it kept getting caught on stuff. Hope its ok, it kind of seemed like her body was pushing it out if you get what I mean, the skin got so thin I got worried she would tear it out, or I would accidentally when we were "rough," plus I prefer her without it even though I bought her a bunch of different ones. So we took it out. It seems to be healing fine.
