Hamsters shed their fur in spring, which is their seasonal molting phenomenon. Hamsters are animals that molt seasonally. They molt every year in spring and autumn to adapt to the seasonal changes. Spring molting usually occurs from March to May, and autumn molting occurs from August to October.

The main reason why hamsters shed their fur in spring is to adapt to the seasonal changes. During the transition from spring to summer, hamsters need to shed their old fur and grow new fur to adapt to the hot summer. While during the transition from autumn to winter, they need to molt to adapt to the cold climate. In addition, factors such as poor nutrition, an unsuitable living environment, and skin diseases can also cause hamsters to shed their fur.
To help hamsters get through the molting period smoothly, owners can provide a balanced diet, keep the living environment clean and at a suitable temperature, regularly check the health of hamsters, and promptly detect and deal with possible skin diseases.
