vanishing over night

There are many different reasons why a mother rodent will kill/eat their young:
-Not enough food/water
-Not enough space
-Baby was sick
-Baby died
-First litter

Didn't say that was the only reason but if you read more of what the op said they have plenty of food and water plenty of space. Actually I read the inbreeding thing from the site owners FAQ.

my mom never went to college thank you very much.
