Well, it is a long story you can read in my other posts, but the short of what I am wondering now is, could one of my new rats be pregnant? We have had them now for 4 days. The youngest is around 4/5 weeks, and I am pretty sure she was in heat already, hoppin' around like a spaz, and wiggling, (maybe just baby stuff, but I mean really spastic, lol, but the other one, the older one, is approx. 6 weeks I think, has me wondering. She sleeps at least twice as much as the other rat, but is healthly looking, and playful when she is awake. No signs of illness, just, very sleepy. Right now the younger one is playing downstairs and the older one is sleeping up stairs. When she was sound asleep earlier she suddenly jumped and squealed, looked around and then curled back up. Ratty dream? I'm worried because she is so young, it just can't be good for her if she is pregnant. I guess all I can really do is wait and see. Anyone have experience with rats this young? Could she just be missing a particular rat from her old mischief?
