As children we where all taught to share, But why share with an invader who carries over 60 different diseases into your home  not to mention ticks and fleas.  Mice really have tinny bladders so they spray urine every where they go up to 3000 micro drops a day.  They contaminate our kitchens with there droppings but what is going on in your walls is the real danger.  Mice like to chew on plastic and rubber and any electrician can tell you what they do to your wiring.
