Behavior:

  • In houses, pack rats are active nocturnally, searching for food and nest material.
  • A peculiar characteristic is that if they find something they want, they will drop what they are currently carrying, for example a piece of cactus, and they will “trade” it for the new item.
  • They are particularly fond of twigs, stones, dog poop, and shiny objects, leading to tales of rats swapping jewelry for a stone.
  • Herbivores: Feed on nuts, seeds, fruit, and foliage

Facts:

  • There are approximately 22 species of packrats in the Southwest, including Arizona.
  • Nests are often called “middens” and have been discovered clear back to the ice age.
  • Packrats will make tapping noises with their feet when they are disturbed.
  • Females produce 1-2 litters a year, with 2-6 pups in each litter.
