House mice are very small weighing only 2/5 to 4/5 of an ounce! They have a pointed nose, protruding eyes, and large ears (think Mickey Mouse). The tail of mice is long, making up 50% of their overall length, and hairless with noticeable scaly rings. The coloring of mice varies but they will commonly have grayish brown fur with a buff colored belly.

Field mice are about the same size, but differ in color. Field mice, also called white footed mice, have both a white belly and feet.

They are quite agile with the ability to climb a vertical wall and jump a vertical height of 12 inches!
