The Western European hedgehog is a beloved insectivorous mammal found across gardens, hedgerows, woodlands, and farmland from Western Europe to Scandinavia. Its iconic coat of approximately 5,000 hollow, keratin spines — modified hairs — serves as a near-impenetrable defence when the animal rolls into a tight ball. Despite being one of Europe’s best-known wild mammals, populations have declined dramatically in recent decades due to habitat loss, road casualties, and reduced invertebrate prey.
