Yes. When I fostered a litter I got a nice chomp from momma the day before she delivered. Give her some paper towels to shred and some yummy tidbits to snack on, dim the lights, make sure cage is clean and food and water are full, and leave her alone for a while. You will know if there are babies, trust me- no need to disturb her to check visually. They are LOUD!

Good luck! I adopted a pregnant girl from a pet store a few years ago (she had 16 babies) and it was quite an experience! There's nothing like seeing those little pinks worms grow into adorable, friendly, loyal pets! I'm sure you will provide a great, loving home!

You could neuter the boy too and keep them together eventually (:

IMHO, which is worth exactly what you paid for it   she is pregnant- she was in with males too long not to be, if she is fertile, and there is no good reason a girl that young would be infertile. Just relax and give her some love and some privacy, and watch for signs of nesting- if she suddenly starts shredding everything in the cage and dragging it into her hut, she may be getting ready. The weight gain you are describing also sounds like pregnancy. If she is not very far along, then all the better- you have time to make friends with her before she pops, so she will hopefully be more relaxed about the daily socializing you'll be doing with the babies.

the largest litter i've ever seen was 25  your boy seems to be a bareback (same as one of my girls) and he is adorable! are you keeping her in a cage or tank? i've been told they should be in tanks to avoid injuries (falling etc) or babies through the bars, good luck, i hope she's preggers, little rittens are so cute!

You are joking aren't you Queen Rat?

First litters are supposed to be small?     Some one should have told Sal that.

My pet shop girl Sal was nipping and mouthing for the day before she gave birth.  Give her some time to herself, don't take her out, give her some yummies and see how she goes.

She made a nest last night....right in the middle of her cage....not in any hiding spot!! She weighs 10.8...another 5 oz...so we shall see!!!

Agreed!

NO babies yet, but she sure is grooming her belly alot!!!

Just relax! If she's going to have babies, she'll either do it on her own when she's ready, or you will KNOW there is something wrong. Most rats deliver just fine on their own schedules. If not, you'll know in a few weeks.

6 days!!!

With all due respect, while baby rats are cute, do you realize how many neglected, abused, unwanted rats there are? There's rats in shelters. Pregnant rats in shelters. I think it would be much better to adopt one of them than to wish pregnancy on a young rat just because baby rats are "cute".

If anything, we should wish that she's not pregnant, I think that would be better for all parties.
