Hamsters usually are active at night and sleep during the day. Hamsters are nocturnal animals. During the day, they typically choose quiet and dimly lit places to rest. At night, however, they become active and engage in activities such as foraging, playing, and other daily routines. Hamsters sleep for about 12 to 14 hours, mainly at night, but their sleep can also be interrupted by activities like foraging.

Reasons for Hamsters' Nocturnal Habits
In the wild, due to the large number of natural predators, it is easy for hamsters to be discovered if they are active during the day. Therefore, they choose to be active at night to avoid predators and search for food. This habit has been retained even after they became pets. In addition, hamsters' vision is more acute at night, which enables them to better adapt to the dark environment.
How to Take Care of Nocturnal Hamsters
To take better care of hamsters, the following points should be noted:
- Provide a quiet and dim resting environment: Avoid direct sunlight and noise interference during the day, and avoid disturbing their activities at night.
- Keep the cage clean: Clean the cage regularly to ensure an adequate supply of fresh food and water.
- Install a silent running wheel: Prevent the noise of the running wheel from disturbing people's rest.
