I got a breeding pair of siamese rats on 10/10/11 and on 10/11/11 I know they hooked up at least twice that night because I saw it. After that she went into her hide I watched them for a couple minutes and she didn't come out again at least while I was watching. Basically I was wondering since they only breed when the female is in heat and since I know they hooked up at least twice surely they hooked up several times during the night and into the morning and she is pregnant right? This is my first time breeding my own rats and if it works out i'll get more to feed all my snakes and maybe some rabbits too for the burms and retics.
