Mice seek out secure nests, as they have very short lifespans when exposed to the elements in the wild. This has led to several adaptations for survival, such as a preference for inhabiting buildings and gaining the ability to reproduce very quickly after birth.

Mice can also change some physical characteristics very quickly when forced to inhabit new environments. They grow thicker coats when living outdoors in cold environments. The ability to change coat color very quickly has also been exhibited by the rock pocket mouse, which has to change coat colors quickly in the wake of volcanic eruptions to avoid being exposed to predators.

Mice also easily adapt their diets to whatever is available in the area. Mice who live in forests hunt insects, field mice eat grains and seeds, and mice that inhabit human dwellings eat nearly any food that they can reach but particularly like foods high in fat.

Deer mice have also shown adaptation to high altitudes through changes in their blood composition and a dietary preference for carbohydrates.
