Not sure why the snake is soaking. You can feed him as much as you want or what he'll take, I did that for my first snake I got and now I'm lucky if she'll eat once a month. It sucks, keep them on a schedule, which I use the word "schedule" loosely since sometimes mine goes passed the 5-7 day mark. These snakes can go months without eating, you do not need to feed that much unless the mice are really small.
