Poop gets a bad rap, but it’s really very cool and useful. Animals use poop in many different ways: to trick predators and prey, send messages, feed themselves and their babies, build homes, mark their territories, and more. Young readers will discover why rabbits, hamsters, pigs and gorillas eat their own feces (gross!), why some ground-nesting birds circle their eggs with poop, and how caterpillars can build umbrellas made of poop to hide under. There are so many ways to use poop, it is a shame to waste it.
