The weight of a pet hamster is greatly related to its breed. There are many kinds of hamsters, mainly divided into five categories: Syrian golden hamsters, Campbell's dwarf hamsters, Djungarian hamsters, Roborovski hamsters, and Chinese hamsters. The normal weight of an adult Syrian golden hamster is 80-160 grams. The normal weight of Campbell's and Djungarian hamsters is 40-60 grams. The normal weight of Chinese hamsters is 30-50 grams. The normal weight of Roborovski hamsters is 25-40 grams.
The growth process of hamsters is divided into several stages: infancy (before three months), adulthood (from three months to one and a half years old), and old age (starting around one and a half years old). The body size and health status of hamsters are different at each stage. Especially in old age, the physical functions of hamsters begin to decline and they are prone to health problems.
In general, the weight range of pet hamsters is very wide. From infancy to adulthood, the weight will change, and there are also differences among different breeds. Therefore, the specific weight depends on factors such as the breed, age, and feeding conditions of the hamster.
