Molly's a mummy!

Okay so on 28th November 2010 unfortunately my pet mouse Izzy died and so I got a new mouse to replace her called Molly, when we bought her we noticed she was quite big, but i thought she was just fat from food. My parent went away on a holiday a few days after we had bought Molly. When my parent had came back we found lots of baby mice hidden well and low under Molly's newspaper nest we figured these mice belonged to Molly as we saw them feeding from her. But when baby mice are first born they are small and pink. But these (9!!) mice were bigger than when mice are when they are first born and they were fluffy although their eyes were not open yet. So we figured we bought Molly from the pet shop whilst she was pregnant and she had had them a few days after my parent had left on their holiday. So this was very unexpected as I am not a breeder and I had two female mice, no males. So with that we will be giving them to the pet shop we got Molly from.
