My rat Rosabella had 10 beautiful little healthy babies on April 7, 2003, and they are all still alive so I think they'll stay alive . But I have no idea how to sex them! I need to find out soon because I need to line up homes for them, and some people won't take boys, others won't take girls, it's madness! And their little parts are so small and they all seem the same to me! Please, someone, tell me how to tell them apart! Thank you! -Lila
