How do you teach a pet mouse to come when it's name is called?

Hold a treat in your hand and call your mouse's name. It will come forward in attempt to get the treat. Keep calling his or her name until he or she gets the treat. Say it's name once more before giving the treat to your mouse. keep getting farther back each day you teach your mouse this trick. It should take 14 to 21 days to teach this to your mouse without holding a treat.
