Hi. My Syrian hamster had babies and they are 9 days old. Since yesterday, mom hamster started coming out of the nest more often and I find her sleeping in the corner of the cage. Is it normal ? Does this mean she abandoned the babies or she thinks it's OK to leave the babies a little while since the babies are getting older? Eventually mom hamster goes back into the nest and babies seems to be growing (somer are bigger than the others) but I'm still worried why she spends time away from the babies.
