It is impossible to tell by physical examination alone when they are babies since their genitals are mostly internal, and the testes in the males often don't descend for a couple of months, if at all. Because of that issue and aggression - which can be fatal, it is usually safest to house hamsters individually. If you try to separate a large litter by gender, you may still end up with unintentional inbreeding. That is because the testes in the males sometimes don't fully descend or they descend late, thus leading to erroneous conclusions about their gender. Now, if you observe them attempting to mate, there is no mistake (though it may be too late to prevent pregnancy by the time you catch them), since the male's genitalia will be visible.
To know a hamster's gender, you must hold your hamster very carefully and turn it so that its belly is clearly visible and check for a penis. If not, your hamster is a girl, if so, it is a boy. You could also try this website...http://www.hamsterific.com/HamsterUniversity/SexingHamsters.html
That depends on the age of the hamster. Newborn hamsters are very small and have no fur. They can't see or hear; they can only smell. They pull themselves along by their front feet. At two weeks old the hamsters are still small but have soft furry coats. After this age your only real indicator of their age is how small they are or how active they are. You have no real way of telling the age exactly.
The simplest way i can say this is: You can tell if your hamster is a boy by looking underneath it! If it is a boy after a few months of birth you will see...well the best i can say is privates. So if it is a girl it will not have privates. :) x
Female hamsters have as many as 16 nipples.
because a boy hamster has something come on his but that's half his body size its his stuff
Boys have a yellow dot in the middle of their tummy.
Their private area is different...if you go to google.com and type in diagram of a hamster then it will show up and show the difference between the two boy and girl.
guinea pigs are much larger
YOu can not tell the difference between a girl or boy starfish.
mice usually have long tails, hampsters have stumps
a girl is brown a boy is black
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 :)
