The common house mouse may be a familiar animal but there are more than 30 known species of the rodents. The small mammals have a pointed nose, a round furry body and a long, near-hairless tail.  They have very large ears and keen hearing. The house mouse is also a popular pet.

Mice can range in color from bright white to a mix of browns and grays. They typically range between 1 to 7 inches (2.54 to 18 cm) in length depending on their species. They are found in nearly every country and type of terrain. There are many varieties of mice including the domestic mouse, fancy mice, spiny mice and zebra mice.

Mice are nocturnal herbivores that primarily eat fruit or grain. Due to their small size, they are an easy target for predators like birds, cats, wild dogs and even foxes. Mice and rats are commonly used for laboratory testing.
