I've got my feeders on Aspen Pellets (available at ur local pet store or feed store). My petstore had a 10 lb bag for like $8 or so, but after I bought that I called around and one of my local feed stores has Aspen Pellets for $.25 a lb And they carry it all year long around here (surpise to me cause this is a SMALL town, heck it took me 8 hours to find a place that carried cypress mulch around here this time of year, and he only had 4 bags left lol).

Anyone live near western maryland and wants some feeders, if u drive u can have them free in a couple weeks after they're born and weened off momma mouse.
