2 - 3 Years
The lifespan of a hamster typically ranges from 2 to 3 years. However, the specific lifespan is influenced by multiple factors such as the breed, rearing conditions, and health status. Here is a comprehensive analysis:

I. Basic Lifespan Range
General Lifespan: The lifespan of most hamsters (such as Syrian hamsters and Winter White hamsters) is between 2 and 3 years.
Breed Differences
Dwarf Roborovski Hamsters: They have a relatively longer lifespan, which can reach 3 to 3.5 years.
Syrian Hamsters (such as Golden Hamsters): It is about 2 to 3 years. With high-quality rearing, it may approach 3 years.
Pudding Hamsters: Their lifespan is relatively short, usually ranging from 1 to 2 years.
II. Key Factors Affecting Lifespan
Rearing Environment
A clean and spacious cage is required, equipped with toys like a running wheel to avoid stress or diseases caused by a cramped space.
The temperature should be controlled between 20℃ and 28℃, and the humidity is preferably between 40% and 60%.
Diet Management
It is necessary to have a balanced intake of protein, vitamins, etc., and avoid giving human foods that are high in sugar and salt.
For sensitive breeds like Pudding hamsters, pay attention to the issue of food transition.
Health Care
Regularly observe their mental state, appetite, etc., and seek medical attention in a timely manner.
Female hamsters that have not given birth may have a longer lifespan than male hamsters.
III. Potential Risks of Low-priced Hamsters
Hamsters that cost around 10 yuan may have weaker constitutions due to poor breeding environments or genetic defects. More attention needs to be paid to the rearing conditions to extend their lifespan.
IV. Suggestions for Extending Lifespan
Provide high-quality hamster food, supplemented with fresh fruits and vegetables.
Avoid keeping hamsters alone (except for Syrian hamsters) or allowing excessive social interaction.
Regularly clean the cage to prevent the growth of bacteria.
Conclusion: Although the lifespan of hamsters is short, through scientific rearing, their healthy years can be maximized. If you are looking for a longer lifespan, it is recommended to choose Dwarf Roborovski hamsters or Syrian hamsters and pay attention to daily care.
