How Do You Tell The Sex Of A Small Vole, Or Field Mouse?

I have 2 as pets and i would like them to breed. If anyone knows any information on this, please let me know. Also, a regular mouse may be the same as far as breeding, so if you know anything about that then it would be helpful as well. Thanks

    To determine the sex in mice examine the distance between the rectum and the urogenital opening--it will be shorter in females.  It can be hard to sex very young males.  A breeder, pet store employee, or veterinarian should be able to help you.  Also by age 6-8 weeks of age the testicles should be visible in most males.  Keeping males together should be avoided.

      This has pictures to help you determine the sex www.thefunmouse.com   It is fairly easy to do, but when flipping the mouse over do not hold it by it's tail the males tend to retract their testicles when you do this.
