As mentioned earlier, mice like to live in groups. This is something that holds for both house and field mice. If you spot a mouse out in the open field, then the probability is that there is a collection of other mice near the area where you have seen the first one. Additionally, mice prefer to stick to a small area and can only travel as far as twenty-five feet in search of food. When food becomes scarce in the fields, they may travel further, although this is not very common.
