If more litters are on the agenda, make sure Mama gets at least a full week's rest in a nice clean cage before breeding her again. Occasionally a water bottle leaks, or some other disaster occurs, which leaves a cage unhealthy for both Mama hamster and new pups. Although the rule of thumb is not to disturb the nest for at least the first ten days, there are exceptions to every rule. Since hamsters, by nature, are clean animals they do appreciate a clean dry house. When changing a cage with new pups, move slowly and talk to mama and daddy in a soft reassuring voice.
Dwarfs are generally quite tolerant.
The most effective method of completing the task of providing a dry cage is as follows. Put a small amount of fresh bedding in a bucket or container for Mom and Dad. Gently remove them from the cage - they may be a little agitated because they are feeling the need to protect their newborn pups. If necessary, scoop them up with a coffee mug and place them in the bucket or container. Now, a soup bowl works great for the pups.
