Hedgehogs curl up as a defense mechanism to protect themselves from potential threats. When they feel scared or threatened, they roll into a tight ball with their quills pointing outwards, creating a spiky barrier that deters predators. This behavior helps them shield their vulnerable belly and face from harm. Curling up also allows hedgehogs to appear larger and more intimidating to predators. It's essential to respect their need for space and time to uncurl when they feel safe again.
