The house mouse is thought to have originated in the Mediterranean, spread to China and from there dispersed with humans to every continent in the world except Antarctica. This is not an endangered species. Humans treat the house mouse as a pest and spend a great deal of money to exterminate them. The house mouse is a great dinner for many predators, including domestic cats, dogs, owls, hawks, wolves, foxes, weasels, mongooses and large reptiles.
The house mouse possesses a small, compact lightly furry body that is able to squeeze into very tight spaces. Coloration varies from grey to brown to agouti – a mixture of brown and black. The underside is a pale color. The small feet and long tail are naked or very, very lightly covered in fur that cannot be seen from a short distance. The house mouse has a shorter pointed face than that of a rat or a shrew.
Life Cycle and Behavior
The house mouse is like a human in that it can breed at any time and not during one particular season. The mother can produce litters up to a dozen babies, although litters average only 5 to 7 babies. After a three week gestation, the babies are born hairless, blind and deaf. The female house mouse has five sets of nipples which can accommodate such large litters. After three weeks, the babies are weaned and on their own. The mother mouse is ready to mate again.
House mice are flexible socially in that they can live singly or in large groups. House mice can eat just any food available to them, including soap, plastic and dead mice.
The House mouse is listed as Least Concern (LR/lc), lowest risk. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category, on the IUCN Red List of Threatened Species
Namings for the house mouseA young / baby of a house mouse is called a 'pinkie, kitten or pup'. The females are called 'doe' and males 'buck'. A house mouse group is called a 'nest, colony, harvest, horde or mischief'.
