Mice in the wild are prey animals to a wide number of different animals, such as birds like owls and reptiles ; hence they are adapted with keen senses and ground, underground , covered lifestyle.



What the wikipedia says

A mouse (plural: mice) is a small mammal belonging to the order of rodents, characteristically having a pointed snout, small rounded ears, and a long naked or almost hairless tail. The best known mouse species is the common house mouse (Mus musculus). It is also a popular pet. In some places, certain kinds of field mice are also common. They are known to invade homes for food and occasionally shelter.

The American white-footed mouse (Peromyscus leucopus) and the deer mouse (Peromyscus maniculatus), as well as other common species of mouse-like rodents around the world, also sometimes live in houses. These, however, are in other genera.

What eats mice?

Cats, wild dogs, foxes, birds of prey, snakes and even certain kinds of arthropods have been known to prey heavily upon mice. Nevertheless, because of its remarkable adaptability to almost any environment, the mouse is one of the most successful mammalian genera living on Earth today.

How they avoid being eaten and find food themselves

Primarily nocturnal  animals, mice compensate for their poor eyesight with a keen sense of hearing, and rely especially on their sense of smell to locate food and avoid predators. 

Diseases associated with mice

Mice can at times be vermin, damaging and eating crops, causing structural damage and spreading diseases through their parasites and feces. 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 (HPS).

Mice and rats are the most commonly used animals for laboratory tests. 

How mice live

Mice build intricate burrows in the wild. These burrows typically have long entrances and are equipped with escape tunnels/routes. There is some evidence from a new study that indicates that the architectural design of a burrow is a result of what is pre-written in a mouse's DNA
