At least in Britain, if you’re cute they’ll build a highway for you – and size it for you, too. From Atlas Obscura:
If you happen to spot a small hole in the bottom of a fence or brick wall in Barnes, a neighborhood in South West London, there’s a good chance that you’ve stumbled upon a hedgehog crossing, and that Michel Birkenwald is responsible for it.
A jeweller by trade, Birkenwald has become one of London’s most enthusiastic engineers of infrastructure for animals. He founded and self-financed Barnes Hedgehogs around four years ago. The group drills the holes for free and generally advocates for the welfare of wild hedgehogs. Once Birkenwald has crafted a passage, he usually affixes a sign reading “Hedgehog Highway,” with the creature’s spiky silhouette.
Definitely an Awwwwwwwwwwww moment. And they have pictures!
