When a hedgehog curls into a ball, it's primarily a defensive behavior. Hedgehogs have a natural instinct to protect themselves from potential threats. This curling action is a way to shield their vulnerable underbellies and face from predators. The spines on their backs act as armor, making it difficult for predators to attack them.

In addition to being a defense mechanism, curling up can also indicate that a hedgehog is feeling stressed or scared. If your hedgehog frequently curls up when you approach, it may be a sign that they need more time to acclimate to their environment or to you as their owner.

However, it's important to note that hedgehogs may also curl up when they are sleeping or resting, as this position can provide them comfort. If you notice your hedgehog curling up in its habitat, ensure that the environment is safe, quiet, and free from disturbances.

To help your hedgehog feel more comfortable and less likely to curl up in fear, try spending time near their enclosure, speaking softly to them, and offering treats to build trust. Over time, they may become more relaxed and less inclined to curl up when approached.
