The expected lifespan of dwarf hamsters is influenced by their species, gender, and care conditions. Details are as follows:
I. Lifespan Range
Average Lifespan
Most dwarf hamsters live for 1.5 to 3 years. Common species like Campbell's dwarf hamsters and Winter white dwarf hamsters typically survive for 2 to 2.5 years.
Roborovski dwarf hamsters (often called "Robos") have a longer lifespan, reaching around 3 years.
Gender Differences
Male hamsters usually live longer than female hamsters, and non-breeding female hamsters tend to have a relatively longer lifespan.
Female hamsters that breed frequently may have a shortened lifespan.
II. Influencing Factors
Species Differences: Campbell's dwarf hamsters (e.g., the "three-line" and "purple-furred" variants) mostly live for 2 to 2.5 years, while Roborovski dwarf hamsters—though the smallest in size—have a shorter lifespan of 1.5 to 2 years.
Care Conditions: Using low-dust bedding, providing a scientific diet (such as high-protein feed), and maintaining a stable environment can extend their lifespan.
III. Special Cases
A very small number of individuals, particularly Roborovski dwarf hamsters, may live up to 3.5 years under ideal conditions.
