There are mice everywhere. From the tropics to the polar regions, in the most remote corners as well as in the middle of the city. But many a small fur animal that we call the "mouse" does not actually belong to the group of small rodents - for example the insect eater bats and shrews.

Mice species

The mice (Mus) are a genus of the real mice, the best known species of which is the house mouse. There are also 37 other species, some of which live close to humans, but some also live in seclusion in the forest.


Mice are between 4.5 and 12.5 centimeters long. In many species of mice, the tail is as long as the body. In voles, which look very similar to house mice, the tail is significantly shorter than half of their trunk. The normal weight of a mouse is around 30 grams, and mice kept in the laboratory or so-called color mice can become much heavier. Mice weighing 60 grams have already been found here! Mice that live in the wild are gray or brown on the top of the body, the underside is light gray or brown in color, or completely white. Due to breeding, however, there are many color variants today. The tail of the mouse is provided with visible scale rings and covered with fine hairs. Mice have sharp-edged incisor teeth with which they can gradually gnaw themselves through strong doors.
