The lifespan of dwarf hamsters varies significantly depending on their species, living conditions, and individual differences. Here are the details:
I. Average Lifespan Range
Most dwarf hamsters live for 1.5 to 2.5 years, with some individuals reaching around 3 years.
Roborovski hamsters (the smallest dwarf species) have a relatively longer lifespan, averaging 2 to 3 years.
Campbell's dwarf hamsters and Winter White dwarf hamsters typically live for 2 to 2.5 years.
II. Key Factors Affecting Lifespan
Species Differences
Smaller species like Roborovski hamsters may live slightly longer than Campbell's or Winter White hamsters.
Male hamsters generally have longer lifespans than females, and females that never breed may also live longer.
Living Conditions
Environment: Low-dust bedding, clean drinking water, and a suitable temperature (20–24°C) can significantly extend their lifespan.
Diet: A balanced staple diet (such as specialized hamster food) is better for their health than a diet of random snacks.
Other Factors
In captivity, scientific care—such as regular health checks and preventing obesity—can improve their lifespan.
