Their soft fur is brownish on top, grayish on the sides and white below. Females produce up to seven litters per year with 3-5 young per litter. They usually live less than a year in the wild.
  • Distribution:   Western harvest mice range from southern Mexico through the western half of the United States. They are found in prairies and uncultivated croplands in Kansas.
  • Food:   Western harvest mice feed on seeds of grasses and wildflowers, young plants and insect larvae. They consume up to one-third of their weight per day.
