How to care for a mother hamster and her babies
Prepare the mother for birth.
If you know the mother is pregnant ahead of time, you can work on preparing her for birth. You can tell a hamster is pregnant if she has gained weight and is engaging in nesting behaviors, such as piling wood shavings and other material in one corner of the cage.
Clean her cage and replace all wood shavings or other substrate with clean supplies. You should also remove wheels and toys to prevent injury to the babies.
