Answer:
First of all, why do you want a mouse in your house?
Anyway, if you want one as a pet, you should go to the pet store. Mice are more sanitary there, and mice outside of the home are rarely seen and are rather skittish. Or you could get a cat and have them bring it up. Anyway, mice outside of the home should be caught with something to protect your hand, like a leather glove as the mouse could be carrying a disease or bite, and that would HURT!
