House Mouse (Mus musculus)

It comes from Asia and is smaller than the wood mouse. It lives on all kinds of terrain not including the high mountains. It can carry diseases although not as many as rats. They are omnivores and can be cannibals above all when the other animal has been caught in a trap. They reach sexual maturity after only a few weeks and gestation lasts for 20 to 25 days. They can have as many as ten litters a year of from three to ten mice each.
