Last night Knothead was only shoulder while I was sweeping his mess and the broom accidently hit the cage...Well he freaked and jumped clear off my shoulder onto the tile floor. He started going around in circles swatting at his mouth. I finally got him calmed down and he started me biting me again so I think he is going to be fine but anything I should be looking for. He hit really hard I checked his teeth and they looked fine, no blood either.
