When in the north of Mexico or Southwestern United States, it becomes impossible to not encounter at least a few cactus mice. These mice prefer to live in semi-arid conditions with sparse vegetation. While they are not much different in comparison with other related species such as the deer mice, cactus mice are known for their large ears and adorable looks.

The cactus mouse (scientific name Peromyscus eremicus) is closely related to deer mice but is not the same. While cactus mouse is native to Southwestern United States, the deer mouse is native to North America. The two species belong to the same genus but have different characteristics.

When it comes to food, the cactus mouse species is pretty adaptive. These mice eat seeds and green vegetation for most of the year. When some insects are available, they munch on a variety of small insects as well.

The species is most fond of the summer season, which is also when most of the reproductive activities take place. The female cactus mouse can give birth to around four pinkies at one time. There can be a maximum of four litters each year. In the winter season, the cactus mice reduce the metabolic activities in their body through a process known as torpor.
