Well, I don't have the room to properly breed rats, not to mention that I don't really have anywhere to send/give the too large adults. I do breed mice, tho, and have some really pretty ones from silver albinos to a black agouti.

I have kept rats as pets before and think they're great. My favorite was my Golden Agouti girl. There is one rat in the house now, a sweet Siamese male, that I'm trying to find a good home for.
