I know this for feeders, but I've gotten attached to some of them and breed them for different things like, color, markings,number of litters and other things. I've really gotten in to the genetics of them...I have gotten a hairless mouse, a silk coat one (satin), but the only other mice I can find around my area are all white and feeders. I'm looking foward to attending this show and pick up some different varieties. Here is the link if anyone is also intrested http://www.mousefancier.com/sefma/events.htm
