Not really no, but boy hamsters are generally larger at the rear end than girls because of their...ahem...."parts"
They're both almost equall in size but the girl is a tiny bit bigger.
Boy hamsters are MUCH bigger and meaner than girl hamsters so I got the girl!
Well if it is a boy, it would be easy to tell as there bums would be bigger than if your hamster is a girl. If you can't tell yet then you could have to turn them other and look at them closer :)
Yes They Are
It all depends on the breed of hamster. Usually rats tend to be bigger when fully grown than a fully grown hamster. And if its a dwarf hamster the rat is definitely bigger.
A long haired hamster, also known as a syrian hamster, can grow up to 5-6 inches. Even though they have longer and messier coats types than a short haired hamster, a long haired hamster does not grow bigger in size than a short haired. Long haired hamsters reach their full size a within a year after birth.
Because God made all animals in a variety. No one is the same as the other.
I think you have bigger problems than asthma if you want to use a hamster ball.
the girl is bigger
Nothing, this is normal.
there a few species of dragon fly that are bigger than a hamster but most went extengt around the same time the dinos did
Actually it's the other way around the male has more dominance over the female so therefore they are naturally bigger.
