I am breeding astrex mice :lol: i am probably being silly but I like them so thats that.Can anyone out there give me suggestions on improving their coats,they loose most of the curl in about 6-8weeks. Because I also am working on type I am outcrossing to my more typey mice. 1 mating to a strait coat then the Astrex from that litter mated to Astrex again,Iget beautiful tight curly coats while young but they lose them quickly.please help with ideas if you can
