The lifespan of Chinese dwarf hamsters is generally around 2 to 3 years. Specifically, most dwarf hamsters live for 2 to 2.5 years, and a few can even reach the age of 3 years. The main factors that affect the lifespan of dwarf hamsters include differences in breeds, the breeding environment, diet, and health conditions.
Main Factors Affecting Lifespan
Breed Differences: Dwarf hamsters such as the Winter White Dwarf Hamster (Three-line Hamster) and the Campbell's Dwarf Hamster (One-line Hamster) usually have a lifespan of 2 to 2.5 years. On the other hand, Syrian hamsters (Golden Hamsters), due to their larger size, have a relatively longer lifespan and can live up to 2.5 to 3 years.
Breeding Environment: A suitable breeding environment has a significant impact on the lifespan of hamsters. Hamsters need enough space to move around, and the temperature and humidity should also be controlled within an appropriate range. For example, a Syrian hamster requires a cage that is at least 30×30×30 centimeters in size, with the temperature maintained between 18 and 26 degrees Celsius and the humidity between 40% and 60%.
Dietary Factors: A nutritionally balanced diet is crucial for the health of hamsters. A hamster's diet should include high-quality hamster food, an appropriate amount of fresh vegetables and fruits, as well as clean drinking water. Feeding a single type of food for a long time will lead to an unbalanced diet, which can affect their health and lifespan.
Health and Genetic Factors: Genetic defects or health problems can also affect the lifespan of hamsters. If the parents of a hamster have genetic defects, the probability of the offspring having health problems will increase, thus affecting their lifespan.
