Does she sit on wire at all? She could have sore hocks, which do need to be taken care of.

you could clean it good and put neosporin with no pain relief on it to help it heal if its a clean cut

a warm damp cloth always works for me

Like Monkeybun said… is it possible that it’s actually a sore hock instead of a wound? They’re really easy to miss, and you might not have noticed it until you looked after she bumped herself.

Sore hocks aren’t a big deal unless they get infected, in which case they need vet care. A lot of bunnies get them, even if they aren’t around wire flooring. Sore hocks can develop just from a bunny zooming around a room with a rug or carpet.

I took Remy to a vet once because I was worried about his hocks, but they weren’t infected and he said that, if things proceed naturally, a callous will form there as nature’s way to protect the rubbed skin. Try and check that area and see if it’s pink and callousy, or red and possibly infected.

If it’s pink and callousy, I would advise cleaning it but not putting anything on it like neosporin because that would soften the skin. Let the callous develop naturally.

If, instead, it is actually from the bump on the wall, then just ignore everything I just said : D
