The lifespan of Teddy Bear Hamsters (a type of Syrian hamster) is influenced by factors such as breed and living conditions. Based on highly reliable information compiled from comprehensive research, their lifespan range and key influencing factors are as follows:

I. Lifespan Range
Average Lifespan: 2.5 to 3.5 years.
Longevity Record: With scientific care, some individuals can live up to 4 years.
II. Key Factors Affecting Lifespan
1. Breed Differences
Teddy Bear Hamsters (also known as Golden Hamsters/Syrian Hamsters) belong to the Syrian hamster category, and their lifespan is longer than that of dwarf hamsters (such as Winter White Dwarf Hamsters and Campbells Dwarf Hamsters).
2. Living Environment
Cage Size: A cage of at least 60cm in length is required to provide sufficient space for activity.
Wheel Size: A running wheel with a diameter of 17.5 to 21cm is recommended to prevent exercise-related injuries.
3. Diet and Health
A high-protein diet (e.g., chicken breast, shrimp) is needed to maintain a healthy weight (90 to 160 grams).
Regular cage cleaning is essential to avoid bacterial infections.
4. Gender and Breeding
Males typically have a slightly longer lifespan than females (breeding can shorten females’ lifespan).
III. Tips for Extending Lifespan
Scientific Feeding: Prioritize balanced hamster food as the main diet, supplemented with small amounts of nuts, fruits, and vegetables.
Disease Prevention: Monitor the hamster’s appetite and stool condition regularly, and seek veterinary care promptly if any abnormalities occur.
