Could they be pregnant?

[llovelace]

I have 2 female rats, they both had litters and when I was pulling the weanlings, both females looked big, almost like they were pregnant.

So my question is, do they retain sperm? and could they be pregnant?

[Rhasputin]

They can.

Also watch out for worms or mega colon.

Ok, I will put them back in maternity ward then to keep them isolated, Thanks

I notice some of my females swell a little right around weaning their previous litters. I've never really looked into why, I'm assuming it's because of extra calorie intake.

I've never had a female retain sperm so close to having a first litter. Actually, I've never had a female retain sperm at all, that I was aware of.

I wouldn't have a problem putting them back into the main tank, but it's a pimp pad, so I'll let them hang in maternity for a week or 2, to be on the safe side
