Hedgehogs curl into a ball when they are scared as a defense mechanism to protect themselves from potential predators. When they feel threatened or frightened, their instinct is to curl up tightly, with their quills pointing outwards. This behavior helps shield their vulnerable belly and face from harm. By curling into a ball, hedgehogs create a barrier of sharp spines that deters predators from attacking them. This defensive posture also makes them appear larger and less appealing as prey. It's essential to provide a safe and secure environment for your hedgehog to help them feel less stressed and reduce the likelihood of them feeling the need to curl into a ball frequently.
