In addition, hamsters will engage in other activities at night, such as practicing climbing trees, digging and nesting. These activities are quite necessary for them because they can maintain the physical and mental health of hamsters.
If your hamster is active at night, which directly affects your life and sleep, you can consider putting the hamster cage in a relatively quiet room, or turning off the toys in the cage at night to reduce noise and stimulation.
Anyway, it's normal for hamsters to run around at night. They need exercise and activities to keep healthy and happy. If you have any questions about the behavior of hamsters, it is recommended to consult a pet veterinarian or a professional pet owner.
