Animal Wildlife | Mouse | The mouse is a small rodent that is spread across almost all countries. The mouse can be found in all corners of the globe, including parts of Antarctica. Many people today like to keep the mouse as a pet because of its small size and calm temperament of a mouse. The mouse is also widely used in scientific research, even if the mouse is not an easy animal to investigate.
Mice are characterized by the pointed nose, small rounded ears and a tail long and thin with no or little hair. In all but the most restrictive use of the term (genus Mus), the main difference between mice and rats is a matter of size, with relatively less expensive, maybe 12 centimeters (5 inches) or less are considered mice and similar animals looking more like rats designated. Such as rodents, mice and rats, characterized by teeth specialized for gnawing, only one pair of upper incisors, one pair of lower incisors, and a hole followed by one or more teeth and no canines play and not more than one tooth in each quadrant.
Although often regarded as pests, mice play important roles in laboratory research, ecological food chains, and as pets. The best known mouse species is the common house mouse (Mus musculus). It is found in nearly all countries and, as the laboratory mouse, serves as an important model organism in biology and is also a popular pet. The American white-footed mouse (Peromyscus leucopus) and the deer mouse (Peromyscus maniculatus) also sometimes live in houses (though they are not included in the "house mouse" category, nor are they included in the genus Mus). These species of mice generally live commensally with humans (that is, they benefit from humans without affecting humans either positively or negatively).
Even if they can live up to two years in the laboratory, mice in nature only average about three months, mainly due to heavy predation. Cats, wild dogs, foxes, birds, snakes and even certain types of insects have been known to prey heavily on mice.
However, due to its incredible versatility almost any environment and its overall ability to live commensal with humans, is considered the second most successful mammalian species living on earth today (the first was the rat).
Somehow, the mice can be harmful pests, damaging and eating crops and spreading diseases, parasites and feces. Western United States, the dust, which is in contact with mouse droppings combined with a mortal (although rarely) Hantavirus. The original motivation for the domestication of cats is believed to have been in their predation of mice and rats with their families.
