Some species also eat grasses, succulents, other green vegetation and insects. Typically, caches are made in small pits on the surface of the soil, scattered over the home range of the individual. The small caches hold only the contents of two cheek pouches. Breeding Some species have 2 to 3 litters a year with 1 to 7 offspring, but usually 2 in a litter. At birth, young are toothless, hairless, wrinkled, eyes and ears are closed, and they show the color pattern of adults in shades of pink.
