"A clump of prickly pear cactus is like a five-star restaurant to a number of small rodents that rely on it in their diets. Certain kinds of rats, mice, gophers and ground squirrels eat prickly pear (Opuntia spp.) pads, fruits and seeds, as well as find shelter and protection among the spiny, thickly growing plants. Some rats and mice rely on the water stored in the succulent plant tissue as a fluid source. Rodents help distribute prickly pear seeds by depositing them in their feces after eating the fruits."
