Food Size

[Gage]

hey guys, just a question for ya.

I have a 27-28" Ball Python, what size mice/rats should i be feeding him? he is currently eating adult mice, 2 a week.

i have tried rat pups, s/he took them readily, but i dont like the quality of rat pups that are available to me, the rat weiling (spelling?) i refused to feed them to him, they smelled as though they had been thawed multiple times and ranked of the feces frozen to them.

the only place that sells quality frozen mice around here does not carry rat pups or weilings, only small (about a 6" body, maybe bigger), medium (about a 7-8" body, maybe bigger), and large rat (a full grown, massive rat...)

btw, i am talking frozen rats/mice, i refuse to feed live.
