A hamster can generally survive for about 3 to 7 days without drinking water. Hamsters have very little need for water, and the moisture in vegetables and fruits can fully meet their body's requirements. However, if a hamster doesn't drink water and there are no vegetables or fruits for it to eat, then it may not live for more than a week. Therefore, during the process of raising a hamster, it is essential to provide water for the hamster regularly.
The owner should note that when giving water to a hamster, raw water should not be used directly. It is best to let cooled boiled water cool down completely before offering it to the hamster for drinking. However, if a hamster appears to be refusing to drink water, it may be because it doesn't know how to use the water dispenser. This situation is relatively common in newly weaned hamsters and rarely occurs in adult hamsters. Since hamsters are animals with a strong sense of curiosity and excellent imitative ability, they are very interested in new things and learn quickly. After observing the actions of other hamsters, they may learn how to use the water dispenser, so the owner doesn't need to worry.
