I am fairly new to the game but I picked up a 2 year old that was always fed live since it hatched. To make sure that he transition well and kept eating I still feed him live like he's used to. I do it with caution and the proper tools(pencil and tongs) in case I have to get in there and rescue my snake. I think that as long as you are careful and respectful of the prey there is nothing morally wrong in feeding live. I have never seen or heard of a feeder crying for 25 min from any of my herp friends who have been keeping snakes for may years. Its usually a quick squeak and its over there is no more air in its lungs and it cant inhale to "cry" because its being constricted. I am also a hunter who has a problem with people who are upset by it saying its wrong to kill an animal wile they eat a burger or steak, cows don't grow on trees. One animal must die in order for another to live, those have been the rules of the game since the beginning of time.
