Do not mean to thread jack,but at what weigh and length does the Bp have to be to eat small mice, is 232g's big enough?
Also to the Op here is a link to a rat/mice size chart,

Try to feed your ball pythons the something the same size as the girth or 25% bigger,or something a little less then half his weight! I know this was not much help but i did not want to seem useless.
