There are reasons why I feed live. My rats are as precious to me as the snakes... they don't die unless they have to. So, when the ball pythons skip meals like they often do, the rats get to live another week.
And about "asking for my snake to get hurt"... today, my son came home with this big gash running down his shin about 1.5 inches wide and 4 inches long. He fell off the playground. He doesn't HAVE to play in the playground... there are a lot of things he can do to expend all that extra energy. So, letting him run around the playground is just asking for him to get hurt. Okay, so what's my point? Well, mainly that boys play in the playground and snakes eat live rats. That's pretty much the way things work around my house. We mitigate accidents by being careful. So far, the boys are still healthy and so are the snakes.
