okay i get it now. i always called the fuzzies pinkies. the adult mice are always really small. i wanted to switch to small rats instead of "large" mice. it seems mice are sold so quikly the stores usualy only have smaller ones. i wanted to start breeding so i can get the perfect sizes for the snakes. as soon as i find a place that has smaller rats i will start feeding those. the mice just dont cut it anymore. 20" is a rough estimate give or take a half inch to 3 inches tops. but mice seem to be too small. what if i fed the mice something calcium rich before death? or what about supliments?
