Peromyscus leucopus, also known as the white-footed mouse, is a common rodent found in North America. Synonyms for this species include Hesperomys leucopus, Mus leucopus, and Peromyscus maniculatus leucopus. The white-footed mouse is a small and agile mammal that typically has white underparts and feet, although its fur color can vary depending on its habitat. While they are often considered pests, white-footed mice play an important role in the ecosystem as prey for larger animals and as seed dispersers. Their ability to adapt to changes in their environment has also made them valuable subjects for scientific research.
