My Daughter loves the little furry guys and she opened the door to give them a treat and the little bugger ran away ! If I don't find it tonight I'll have to feed the rest off as it was the male that dissapeared. I can wait to see if they are pregnant but I don't really want to keep a set if they won't be breeders. My daughter has never allowed any animals out on purpose and is really good with the normal rats these guys are super demon rats![]()
