I fed off one female that did it, but the one that did it this time has had pups before and was a pretty decent mother.

As I stated in my original post, if the food cna't be bought at wal-mart, it isn't an option. Besides, 33 pounds is an aweful lot for less than 20 mice (not to mention, would eat up what money I get which is needed for food at college).

A homemade diet might be feasible. Do you have any links to recipes?
