I picked up a trio a little over a month ago. Both females really started looking like a ping pong ball over the weekend. The first female had her litter on Monday and the other female a litter this morning. I can't be sure but I think I counted 25 between the two. Not huge litters but not bad for their first. Ok here is the pic.
P.S. They decided to turn the hide over and build the nest so I left it alone.
