Description

Cactus Mice are found in habitats with sandy soil and scattered vegetation, from low deserts to rocky foothills. They typically live in burrows, but are also found on the surface in piles of debris, vegetation, or rock crevices. They are active at night, feeding on seeds, insects, and green vegetation, and can become torpid during the day. They may estivate (become dormant, with metabolic rate lowered) during hotter and drier months, so as to reduce water loss. In her lifetime, which is probably about a year, a female can bear three or four litters of up to four young.
