What does a hyena have in common with an owl?

Answer:

Like owls, hyenas eat the entire body of their prey, including skin, hair, bones, teeth, horns, hooves, etc. They use their powerful jaws to crush the bones, and their extraordinary digestive system is capable of digesting the skin and bones, but the hair, hooves and teeth don't digest. Instead, they regurgitate them, just as owls regurgitate owl pellets.
