Your dwarf hamster needs a well-ventilated home, large enough for a food dish and water bottle, a hiding area (if one isn't built in) and an exercise wheel. There should be plenty of room for all cage accessories, and for her to move around freely.

They like to run and play at night and sleep during the day, so be prepared for them to be active and noisy after dark.
Dwarf hamsters can be friendly and social. If raised together, they can live together peacefully (house same gender pairs only).
They have large cheek pouches to carry food, which they'll store in a special hiding place.
You'll notice your dwarf hamster grooming herself a lot while she's awake.
Be careful, if she gets scared, she may bite. Take extra care when awakening her.
Handle your dwarf hamster gently -- scoop her up in both hands and hold her with cupped hands so she'll feel safe and secure.
Special needs
Your dwarf hamster's front teeth never stop growing -- so she needs lots of healthy things to chew on like treat sticks and chews.
Exercise
Dwarf hamsters have tons of energy and need to run on a wheel in their habitat, or in an exercise ball daily.
Please remember that all pets may bite or scratch, and may transmit disease to humans. Keep your pet's home clean and wash your hands before and after handling your pet or cleaning his home.
