Why Does My Hedgehog Do That?
Decode your hedgehog's body language, habits, and quirks with science-backed explanations.
Quick Answer
Most hedgehog behaviors are driven by instinct, communication, or health needs. Browse common hedgehog behaviors below.
🧬 Instinct
Why does my hedgehog foam at the mouth and lick their quills?
Self-anointing is one of the strangest hedgehog behaviors — they encounter a new scent or taste, produce copious amounts of frothy saliva, then contort their body to spread the foam across their quills. Scientists are not entirely sure why they do this.
Why does my hedgehog curl into a ball?
When a hedgehog feels threatened, they curl into a tight ball with their 5,000-7,000 quills pointing outward in every direction. This is their primary and very effective defense mechanism. New hedgehogs ball up frequently; tame hedgehogs rarely do.
Why is my hedgehog so noisy at night?
Hedgehogs are nocturnal animals that become extremely active at night. They can run several miles on their wheel in a single night. The nighttime noise (wheel running, eating, exploring) is completely normal and essential for their health.
