Koala, the hedgehog, has certainly grown in a year - see how little they were a year ago! Hedgehogs can grow up to 12 inches long, and typically weigh anywhere from 5 to 56 ounces! A common misconception is that hedgehogs are related to porcupines because of their quills. Their closest relatives are actually moonrats, shrews and moles! 📸: darcytheflyinghedgehog
