Hedgehogs have several defense mechanisms to protect themselves from predators. Their primary defense is their spines. When a hedgehog feels threatened, it rolls into a tight ball, presenting its spiky exterior to deter predators. The spines are sharp and can be painful to touch, deterring most predators. Some hedgehogs also make a hissing sound or grunt to warn predators to stay away. If the predator persists, the hedgehog may engage in a defensive behavior called 'anointing,' where it licks or chews on substances to create a foamy saliva that it spreads on its spines, making them even more unappealing. This behavior is thought to confuse or deter predators further.
