There are always exceptions, no matter what. Room mate is still wanting rats when we move so looks like we'll probably still get some. It turns out she wanted a girl so she could name her Bellatrix, but we'll probably get boys and she'll still name the rat Bellatrix. I'm thinking of getting a blonde one to name Lucius. When it gets closer to buying them, know that I will be asking you a lot of questions. :)
