The weight of Syrian hamsters (also known as golden hamsters) varies based on age, gender, and individual differences. Here are the specific figures:

1. Adult Weight Range
Overall Range
Adult Syrian hamsters typically weigh between 80–200 grams, with some individuals reaching up to 220 grams.
Females are generally heavier (90–150 grams), while males tend to be lighter (80–130 grams).
Comparison with Other Breeds
Syrian hamsters are the largest among pet hamsters, weighing approximately 4–6 times that of dwarf hamsters.
2. Weight Changes During Growth Stages
Juvenile Period
7 days after birth: Around 10 grams.
1 month old: 50–80 grams.
3 months old: 80–120 grams, entering a rapid growth phase (gaining 10–15 grams per week).
Adult Period
After 4–6 months, their skeletal structure stabilizes, and weight gain slows down.
3. Health Management Recommendations
Obesity Risks
If a Syrian hamster exceeds 220 grams, it’s important to control its diet to prevent diseases like diabetes.
It’s recommended that they use an exercise wheel for over 3 hours daily.
Abnormal Weight Changes
In elderly hamsters, a weight loss of more than 5% within a week may signal illness.
4. Other Characteristics
Body length typically ranges from 12–20 cm, with females slightly larger than males.
Daily food intake is approximately 10% of their body weight (10–15 grams per day).
