How do you take care of a dorf hanster?

Ensure the pet has hamster food and water in his cage at all times. Make sure there is not any excessive moisture in the cage. Keep the hammy at least at 68 degrees. Change water daily. Put a exercise wheel in his cage. Put a good bedding down, they love to be able to bury in the bedding. Be sure to talk and handle him at least 2 or 3 times a week if not daily to ensure he is use to human interaction; otherwise, you'll have a hammy who's always trying to jump out of your hands.

Good Luck.
