Of course, in the wild they aren't in a newspaper lined tub. In the wild the rat has a chance to escape, and so does the snake if it doesn't want to eat. I still don't think feeding live is any more 'natural' unless the snake was given a total hunting experience.... Dangling/tossing in a rat in a box isn't the same, though I can see it's pros and cons.
Our male IS occasionally fed live, when he's being picky. Thankfully he's never been hurt. Came close a few times though!
I don't understand what you mean by hunting experience
