A mouse, plural mice, is a small mammal. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (Mus musculus). Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter.
In certain contexts, mice can be considered vermin. Vermin are a major source of crop damage as they are known to cause structural damage and spread disease. Mice spread disease through their feces and are often carriers of parasites. In North America, breathing dust that has come in contact with mouse excrement has been linked to Hantavirus, which may lead to Hantavirus pulmonary syndrome

In nature, mice are largely herbivores, consuming any kind of fruit or grain from plants. However, mice adapt well to urban areas and are known for eating almost all types of food scraps. In captivity, mice are commonly fed commercial pelleted mouse diet. These diets are nutritionally complete, but they still need a large variety of vegetables.
Mice do not have a special appetite for cheese. They will only eat cheese for lack of better options.
