Three years ago, my family got a wildlife camera. We began to put it out every night before collecting it the next morning to take a look. One day we noticed something odd on the footage - a hedgehog walking through our hedge! We didn’t even know we had hedgehogs!
That hedgehog probably came into the garden under a gap in the fence. We set up the camera every night, until one day we had close ups of a hedgehog!
Next, we got a hedgehog house. Placing it near the gap, so that hedgehogs could sleep there overnight. We were rewarded with many lovely videos of hedgehogs happily snuggling up in it. We had begun by putting in dry leaves for the hogs, but soon more hogs came and gathered leaves themselves.
