6. Normally, hamsters will be ready for hibernation in winter. If hamsters are kept at home as pets, they will go into hibernation when the ambient temperature is relatively low. After hibernation, people will gradually wake up with the increase of ambient temperature. However, even if the ambient temperature is above 15 ℃, especially above 20 ℃, the hamster still does not wake up. It is recommended to seek medical advice, because before or during hibernation, the ambient temperature may change, energy consumption, malnutrition, or even illness may occur.
