Have you ever wondered if your hamster is a boy or girl but can't figure it out? It can be really important to figure it out, especially if you have more than one hamster and you don't want them to breed. Sexing a hamster just takes a few steps, including figuring out what to look for. Your hamster may not like it when you turn it over to find out its sex, but the process will be over quickly and afterwards you will know if you have cute little boy or girl.
