how odd some comments are like oddball....WHAT DO YOU THINK CRICKETS FEEL WHEN BEING EATEN LIVE BY DRAGONS?...........what you said doesnt make sense like that of a vegen that says I cant eat meat killing is wrong but they eat fish...........the only true reason for not feeding live prey and I mean running around in the enclosure live is the risk of if your snake isnt hungry there and then the mouse /rat has the upper hand and its well known that they will bite and even eat bits out of the snake ,,,your snake is at high risk in this case compared to wild where they can set themselves up in a decent ambush strike the mouse /rat doesnt see the snake but in a controlled enclosure this is not the case the mouse knows what its in for and of course its going to react the snake cant set itself up in a ambush style attack and so its vunrable ...people that do this dont have the concerns and welfare of their snake at heart and really shouldnt own one ...:evil:
