Hamsters usually start sleeping in the morning and start to be active at night. Hamsters prefer to be active at night. Under normal circumstances, hamsters sleep for about 12 to 14 hours a day. As long as everything else is normal, it's best not to disrupt your hamster's sleep schedule and worry too much about how long it sleeps. If you need to adjust your hamster's work and rest time, do so step by step and in a proper way.

How to change the hamster's work and rest time:

1. Generally, it sleeps during the day and comes out at night. Hamsters are nocturnal animals, but their work and rest time can also be changed.

2. If the hamster is noisy at night, you can teach it to sleep at night. The main thing is not to let it sleep during the day. When it wants to sleep, give it some snacks, tease it, and let it come out of the cage to play slowly. Slowly, it will have the same routine as you.

3. If the hamster is not energetic and you cannot force it not to sleep, you still need to ensure its rest and adjust its schedule step by step.
