One of our pet store rats had her babies, at least 17, but i thought i counted more earlier. We left her alone for a while, and she kinda strewed all the babies around one half of the cage... a few in a almost pile, but she buried others in the pine (looks like a few died that way), and didnt clean them at all, they still had their cords, and werent cleaned up at all. She wanted nothing to do with them, she even found out how to climb up and hang from the wire of the tub basically.
We left her alone a while longer, and she didnt even stay near them, she kept "hopping" on two feet, with two feet up on the side of the tub like she thought she could get out.
We dropped 7 babies in with a mother of 5 from yesterday, she is currently warming them up (the babies were ice cold at that point). We then tossed 4 more in with each of the mothers who had babies about a week old... in with the pile (they each had 6-7). So im hoping that they might pick up where the other mother left off... at worst case scenario, the same thing happens that would have if we had left them be..
The two that died in with the original mother were pink and good looking, not like a still birth.
