When they start fighting.
yes they are
No
When they are about 4 months old.
yes boy hamsters are more aggressive then girls
my hamsters did that so i guarantee this will work. what you do is put them in separate everything. for example separate cages
Word of advice, NEVER put two boy hamsters in the same cage. Just putting two in separate cages next to each other can be dangerous.
Separate the genders, like boys in one box or cage and girls in the other, or they will start having babies with their siblings. Also remove boy babies from their mom at three and a half weeks or mom may become pregnant with one of her kids!! Gross!
Girl and boy hamsters smell exactly the same there is no difference.
Girl hamsters behave best they are more calm. Boy hamsters like to fight
Not really no, but boy hamsters are generally larger at the rear end than girls because of their...ahem...."parts"
Its better for you to separate the hamsters if they are fighting.
Two same-sex hamsters tend to get along well with each other, regardless of gender. However, it's usually recommended to keep hamsters of the same sex together to prevent unwanted breeding and potential aggression. So, two boy hamsters or two girl hamsters can make good companions, but make sure they have enough space and resources in their habitat.
