When feeding my young ball, he grabbed the small rat at a bad angle and she was able to bite him. He was starting to shed so at first all I could see was the torn shed and no real damage. He shed that night and it was a little rough but it all came off. But there was a little blood on the area the rat bit and when I check him I could tell there was some damage but I can't tell if its bad or just surface. He seems fine and is just as active as normal. Don't know how to post pics but I took a few.
