Congrads on a new family member, how old is your little man? a female is really not a good idea as they will constantly breed and it is unfair and unhealthy for the female to have back to back pups. females do better in coloneys, males will fight to the death in almost all cases, including brothers. However youd be happy to know that male mice are pretty happy living on there own. I dont get how using home bred pinkies is classed as animal cruelty ?
