Rabbit losing hair on back feet

[Honeybun]

An area on top of each back foot is bare. The skin looks healthy, so I don't think it's mites. Might it be from urine?

It was urine I'd expect irritation of the skin. Not sure what it would be though!!!

How curious... I'd expect irritation of the skin if it was urine, or mites, or fungal issues. But just missing fur on top of the feet? I have no idea. :shock:
