Western hognose bit itself when being fed (Not the Video actual situation).

My female western hognose bit itself by accident when I was feeding her. She missed the target and started chewing on it’s tail. Luckily I got her tail out of her mouth in time but she was able to go deep enough to draw some blood out. I was wondering if I should do anything for the bite because she seems happy and doesn’t seem to be bleeding anymore.

I would switch to a paper towel or paper substrate, if that's not what you are currently using. This will prevent any dirt getting in the wound, will make it very easy to spot any feces and switch out the paper towels, and will let you see if it starts bleeding again very easily. I would also put a tiny bit of neosporin, only on the wounds. Make sure it is just plain neosporin, not the kind with pain relievers. Other than that, just monitor the wounds. Again, the paper towel substrate will greatly help you to keep the cage clean, prevent infection, and see how the healing is doing.
