Other Names: Common House Mouse, Domestic House Mouse
Excellent hearing, smell and touch have enabled the mouse to be highly adaptable to homes and indoor buildings. All they need is a 1/4" opening to be able to enter a building, so they often have access to many places along the building's perimeter.
Another indication that mice are present is a strong musty odor. Cats and dogs may excitedly sniff and probe an area where rats or mice are present, and often indicate this by scratching or making unusual sounds.
