Conservation Status: Least Concern.

A medium-sized rodent with large ears and eyes, the Cotton Deermouse is dark golden-brown above with white underparts and feet. It is very similar to the White-footed Deermouse, with which it breeds in captivity. Although Cotton Deermice prefer to live in such wet habitats as bottomland hardwood forests, hammocks, and swamps, they also tend to inhabit buildings, making them well known to people in the southern United States. With average longevity of only 4-5 months, female Cotton Deermice must mature and reproduce rather quickly. Gestation lasts 23 days. Weaning occurs at 4 weeks, when the young reach about 85 percent of adult weight. The Cotton Deermouse is truly the all-purpose mouse: ridged feet help to make it an agile climber, and it is also a good swimmer and diver. It is an omnivore, eating most anything available.
