If any snake is raised being fed on a live diet, than the chances that they will make a mistake(have an accident) is very low. They seem to be more content with their environment and have many other pyscological benefits. I tell people that if a snake was raised with pre-killed or f/t and then given live,even once, then the risk is higher of making a mistake in the process of killing it. I am always there to watch it happen, because the most careless thing someone can do is leave a live prey item in with the snake for any amount of time and not watch, unless you have a problem feeder. you can tell right away by the snake's first response,if it is interested in the prey or not, and if not, you remove it quickly. that is all there is to it. under these circumstances, none of my snakes have ever gotten a bite/scratch/cut, etc. For me, live feeding has never been a problem or concern.I always do feed in their cages, as they recognized the smells of their environemtent and will be comfortable hunting in their own cages. Try to be there when you feed, just in case a large piece of lets say mulch,bark gets caught on the mouse, you want to pull it off if you can, to avoid compaction.
