But about bringing the snake over to your friends house every week for feeding that could be stressful on the snake and not to mention a big hassle for you and your friend every week to coordinate.

What about just letting your son feed the snake. He is 14 he could easily handle feeding the snake a F/T mouse or rat, or even a live one if thats the route you go.
