I supervise feedings once rats reach weaned size so I'm not worried about my snakes getting hurt. I have fed live for years and only had one incident where my BP didn't grab the rat fully by the head, but I was right there with my tweezers to make sure it couldn't bite her. I don't mind feeding F/T if it's necessary, but in my opinion, the unique thing about having a predator as a pet is to watch it hunt.
