Let’s discover the truth!

What Are Hedgehog Spikes?

Hedgehog spikes are not sharp weapons like porcupine quills. They are actually stiff hairs made of keratin — the same material as our fingernails!

When a hedgehog feels scared:

  • It rolls into a tight ball.

  • The spikes point outward.

  • Predators cannot easily bite or grab it.

Smart, right?
