There are several species of mice, but the best known mouse species is the common house mouse. This type of creature is found in nearly all countries across the world. For some, mice are also popular pets. Although they may live up to two years in the lab, the average mouse lives only about 3 months in the wild, primarily due to heavy predation.
General Mouse Facts
The house mouse is just about what you'd expect a mouse to be - small (3 to 7 inches), gray-brown, with an almost naked tail as long or longer than its body and weighing less than an ounce.
The nocturnal mouse will eat about one-tenth of its weight each day. Its origin is in Europe, but after accompanying the early settlers on their ships to the New World, the mouse has since established itself almost continent-wide.
Although they may live up to two years in a lab, the average mouse lives only about 3 months in the wild, primarily due to heavy predation. Cats, wild dogs, foxes, birds or prey, snakes and certain kinds of insects have been known to prey heavily upon mice.
Nevertheless, due to its incredible adaptability to almost any environment, and its ability to live commensally with humans, the mouse is regarded to be the third most successful mammalian species living on Earth today, after humans and the rat.
As you may guess with the name house mouse, these creatures prefer life indoors, whether it be an apartment complex or single-family dwelling.
Mice prefer the comfort of niches between walls and behind cabinets and appliances.
The house mouse has a very prolific reproductive system breeding year round and having as many as eight litters annually.
Female mice can start having their litters at the age of one and a half to two months. Life expectancy for a wild mouse is no more than one year.
Mice have a diet of a variety of foods, such as seeds, grains and nuts. These little critters requiring only about 1/10 ounce of food each day, and can live without access to fresh water as long as their solid food is fairly moist.
