Did you know a baby porcupine is called a porcupette? These cute critters have soft hair mixed with barbed quills that stick up when they feel threatened to deter predators. Porcupines sleep in trees and feed on the inner bark, twigs and leaves. They live to be 5-6 years old and have one or two young, which are born with soft quills that harden within an hour.
