Labels:text | font | screenshot | white OCR: Pack rats are also called desert wood cats. They often live near cholla cacti. Pack rats collect fruit and seeds in the spring and summer months to store away for winter. These stores are covered with anything the pack rat can find - sticks, stones, leaves or other debris. The store is then covered with the spiny joints of the cholla cactus to deter other desert animals from raiding the pack rat's nest.
