A teddy bear hamster usually stops growing at about six-eight inches. But mine only got up to four in her life.
About 4 to 9 inches mines an adult and she is about 8 inches
4-9 inches...your welcome!...
It get to about 4/9 inches
Sometimes about the size of an adults hand...well my sister had one she said it got pretty big but I think sometimes 4-9 inches?
My teddy bear hamster is still a baby and he is 4in
If they're an adult, they're usually the size of a ginua pig.
