30–1,000 Grams (Varies Greatly by Species)
Hamster weights vary significantly by species. Based on highly authoritative search results, the weight ranges for major species are as follows:
1. Typical Weights of Common Domestic Hamster Species
- Syrian Hamster (Golden Hamster): 110–125 grams. Adult females are slightly larger than males.
- Teddy Bear Hamster (e.g., Syrian “Golden Bear”): 80–200 grams, with some individuals exceeding 200 grams.
- Campbell’s Dwarf Hamster: 35–60 grams. Moderate in size and active.
- Winter White Dwarf Hamster: 30–45 grams. Ideal for新手 (beginners).
- Roborovski Dwarf Hamster (“Dwarf Winter White”/“Grandpa-Grandma Mouse”): 25–40 grams. The smallest and most sensitive species.
2. Key Factors Influencing Weight
- Species Differences: Golden hamsters (12–20 cm in length) are significantly larger than dwarf species (e.g., Roborovski hamsters are only 4–5 cm).
- Feeding Conditions: Overfeeding can lead to obesity, while poor nutrition results in low body weight.
- Health Issues: Obesity may cause cardiovascular diseases and joint strain. Regular weight monitoring is essential.
3. Notes
- Discrepancies in Authoritative Data: Some encyclopedic sources (e.g., "pet鼠" [pet rats]) cite an overly broad range (30–1,000 grams). Always reference specific species for accuracy.
- Juvenile vs. Adult Differences: Young hamsters are lighter, and weights stabilize in adulthood (e.g., Golden Bears reach 120–200 grams after 8 weeks).
- Recommendation: To accurately assess your hamster’s health, refer to the standard weight range for its species and weigh it regularly to monitor trends.
