The average lifespan of the Russian dwarf hamster is approximately 2 years. According to research, the lifespan of Russian dwarf hamsters usually ranges from 1.5 to 2 years. Factors that affect the lifespan of hamsters include genetics, diet, living environment, and care.
For example, excessive breeding will shorten the lifespan of hamsters. Female hamsters that have not given birth generally live longer than male hamsters. In addition, the age of a hamster can be estimated by observing its fur and activity level. The fur of an older hamster will become thinner, and its activity will decrease.
