The House mouse   It is mainly a house dweller, but may live out in the fields either for part of the year, or for the whole of the year in small numbers,Mice eat much the same kind of food as do human beings, including meats, grains, cereals,seeds, fruits and vegetables. Mice will visit a food supply on average 200 times per day, thus a lot of damage is caused due to their eating habits. Unlike the rat, the mouse can exist without water for long periods, if moist foods are available.
