Even if being careful, bites may happen feeding live. If they do, they just need to be kept clean and keep an eye on them. Miqula, my Super Pastel, won't eat anything but live - and her last feeding, she somehow managed to grab her mouse by the tail. Usually she's great with a neck bite and immobilization. This time, she got hold of the tail... and the tip of the tail, at that, and wasn't going to let go just because of it. Before I could do anything about it, she'd coiled on the tail and body - but in the process, she got several small bites on her belly and tail. She had the mouse dead and eaten within minutes, but she does have some bite marks. That was five days ago. Since then she's shed - a complete shed, eyecaps to tailtip, though she managed to shred it into pieces in the process of it coming off - and with her in a nice clean tub on unprinted newsprint paper the bites are almost completely gone now and they never seemed to bother her at all.
