What are baby porcupines called?
In order to protect the mother from injury as she gives birth, a baby porcupine , or porcupette, has soft quills made of hardened hair. After only a few days of life, the porcupette's quills harden because of a substance called keratin that coats them. This creates the sharp, hard quills that are the trademark of a porcupine. A porcupine uses these sharp, needle-like quills to protect itself when danger is near. Source: Reference.com
