Set up the cage, food, water, and exercise toys before you bring the hamster home.
Put the hamster directly into its new environment.
Leave them alone for a few days, only disturb the case as needed to change food and water (or if necessary) clean the cage.
Some rules...
* Don’t poke fingers into the cage or allow loud noises near the cage.
* Early in the evening is the best time to make strides in training.
* Don’t try to hold a hamster while it’s sleeping or eating.
