Hedgehogs puff up as a natural defensive mechanism. When they feel threatened or scared, they will curl into a tight ball and raise their quills to protect themselves from potential predators. This behavior is instinctual and serves as a way to deter threats. For example, if a hedgehog encounters a loud noise or an unfamiliar animal, it may instinctively puff up to make itself appear larger and more intimidating. Additionally, this behavior can also occur when they are in a new environment or during handling if they feel insecure. It's important for hedgehog owners to create a calm and safe environment to minimize stress and reduce the likelihood of puffing up. Providing hiding spots and a cozy, quiet space can help them feel more secure.
