House Mouse

Facts about this mammal


The house mouse is a tiny mammal which lives in small areas close to food.Athough they are wild animals they live near humans.Some house mouse originally come from Asia.


Following mating time, female mice will normally develop a copulation plug which prevents further mating. This plug stays in place for some 24 hours. The birth period is about 19–21 days, and they give birth to a litter of 3–14 young (up to six to eight). One female can have 5 to 10 litters per year, so the mouse population can increase very quickly.


They live in a wide choice of hidden places near food sources, and construct nests from various soft materials.House mice primarily feed on plant matter, but are omnivores. They will eat bacteria in their intestines.


House mice also rely on pheromones for social communication, some of which are produced by the preputial glands of both sexes. The tear fluid and urine of male mice also contains pheromones, such as major urinary proteins. Mice detect pheromones mainly with the vomeronasal organ Jacobson's organ, located at the bottom of the nose.

The urine of house mice, especially that of males, has a characteristic strong odor.


Male aggression occurs in commensal populations, mainly to defend female mates and protect a small territory.The high level of male aggression, with a low female-female aggression level is common in pogamous populations.
