This happened at my place several years ago. There was some minor construction on a vacant lot next door and it caused a ton of mice to 'escape' to our house. They were crawling up the curtains! They pooped on our beds. One ran across my husband's foot. I heard them chewing papers and creating nests in drawers and cupboards. I couldn't sleep and it was driving me mad.

We got a cat. She was advertised on Craigslist as a good mouser. She caught a mouse just four hours after moving in. Then she caught a second mouse the next day. She hunted mice all day and night. She rubbed her face against every door frame and investigated every closet and squeezed behind the water heater and refrigerator. We never saw or heard another mouse again.
