I know this tag is in a sort of "what do we do with it" limbo, but I've been seeing it get added to posts with dickgirls. It's likely that female cat_ears posts would be tagged with female regardless of the implication, and having a few posts with temporarily untagged genders is probably better than dickgirl showing up in female searches (especially when it isn't obvious that it is the catgirl tag that is causing it to show up).
Ideally I'd say we just alias catgirl -> cat_ears and just deal with the cleanup from there, but I'd be fine with at least getting rid of the female implication just to keep the request simple to handle.
