The lifespan of gray dwarf hamsters depends primarily on their breed and living conditions. Here are the details:
I. Average Lifespan Range
Common gray dwarf hamsters (such as Campbell's and Winter White dwarf hamsters): Typically live 2 to 2.5 years.
Roborovski hamsters (also known as "Robos"): Have a longer lifespan, reaching around 3 years.
II. Key Factors Affecting Lifespan
Breed differences:
Winter White dwarf hamsters (including gray-coated variants like "purple" and "pudding" morphs) have an average lifespan of 2 to 2.5 years.
Roborovski hamsters, being the smallest in size, tend to live longer (approximately 3 years).
Living conditions:
Low-dust bedding and a balanced diet can extend their lifespan.
Avoid frequent breeding (especially for females), as reproduction significantly shortens their lifespan.
III. Special Considerations
Male hamsters generally live longer than females.
With scientific care, a small number of individuals may exceed the average lifespan (e.g., some Roborovski hamsters can live up to 3.5 years).
