I am Alexandr Bohler, resident of Rome, Georgia. I am Starting a new, though small rattery. I have just gotten a new rat, an ex-feeder by the name of Ember. I have had many rats in my life and have much experience with raising, but a bit less with breeding. I actually have a question concerning Ember. I thought perhaps she was pregnant when I got her approximately four days ago. Her nipples are visible, which may or may not be a sign of pregnancy, however her vagina is swollen, so I'm not sure if she's pregnant of just in heat. Do Any others have any knowledge in which I may be lacking?
