The frequency of changing the bedding (wood shavings) for hamsters depends on various factors, including the season, the number of hamsters, and their activity level.

Seasonal Factors
- Summer: Due to the relatively high temperature, bacteria multiply rapidly. It is recommended to change the wood shavings every 3 - 4 days to keep the cage clean and well - ventilated.
- Winter: With lower temperatures, the growth of bacteria is slow. You can change the wood shavings every 7 - 10 days.
- Spring and Autumn: The temperature is suitable, and hamsters are more active. It is advisable to change the wood shavings once a week.
Number of Hamsters and Activity Level
- Single Hamster: If the hamster has a normal activity level, the wood shavings can be changed every 1 - 2 weeks.
- Multiple Hamsters: Since the amount of excrement increases, it is recommended to change the wood shavings once a week, or change them in a timely manner according to the degree of dirtiness of the wood shavings.
Observing the Condition of the Wood Shavings
- Odor: When the wood shavings start to emit an obvious stench, they should be replaced promptly.
- Moisture: If the wood shavings become damp and feel wet to the touch, they also need to be replaced.
- Dirtiness: When there are a lot of feces or food residues in the wood shavings, it is also necessary to consider replacing them.
Method of Changing the Wood Shavings
- Prepare New Wood Shavings: Choose unscented and eco - friendly wood shavings and spread them about 2 - 3 centimeters thick on the bottom of the cage.
- Clean the Cage: Transfer the hamster to a temporary container, clean out the old wood shavings and excrement, wash the cage, and let it dry.
- Lay the New Wood Shavings: Evenly spread the new wood shavings on the clean and dry bottom of the cage, ensuring an appropriate thickness.
