The teddy bear hamster has a life span of 2 to 3 years, and the dwarf species of hamster has a life span of 1 to 2 years. The teddy bear hamster is the most popular type of pet hamster, also known as the golden hamster.
Pet hamsters need special care to remain healthy. A decreased life span is one problem for captive hamsters who don't have proper care. A proper diet, fresh water and a clean cage are all important for a healthy hamster. Any hamster that displays matted fur, loses its appetite, has loose stools or appears to be acting differently should be seen by a veterinarian.
