I preferably feed live, pre-killed is fine! When the mouse goes in I wait with a pencil or pen something that "if" Mary J doesn't get the mouse in the head I can hold the head of the mouse up so it does not do no damage!
The only problem with pre-killed is when the snake doesnt wanna eat some ppl make the stupid mistake of putting the mouse back into a bag and freeze it again! BIG NO NO! The mouse has already started to de-compose, so when u thaw it out again and the snake eats it, your snake could de-compose from the stomach out. I've have actually witnessed this happening with a "old" freind of mine and there is nothing you can do the vets can't even help ur snake at this point!
