Key Influencing Factors
Diet: High-protein live prey (e.g., mealworms) paired with fresh fruits and vegetables extends lifespan.
Environment: Maintain temperature at 18–26°C and humidity at 40%–60%.
Health Management: Regularly check teeth and fur; reduce protein intake in old age.
Tip: While Roborovski hamsters have the longest lifespan, their nervous temperament makes them better suited for experienced owners.
