Well... I only have the one girl, and I adore her to bits, but I have to admit that sometimes I wish she would just slow down a bit... she seems to be everywhere at playtime! LOL
With mice, well... I have mixed feelings. About females, I like that they can be kept in groups with no problems and that they smell a lot less than the males, but the most cudly mice I've ever had have been males. Most of the females tolerate handling, jump into my hand and stuff... but the males just LOVE being handled. The only female I've had that acted like the males act was Plumita.
