During the winter, hedgehogs like to hide away from the cold weather in a toasty pile of leaves or another protected spot. Hedgehogs begin to hibernate around December, the best time to put out a hedgehog box. The boxes are expensive to buy but cheap and simple to make. Hedgehogs will enjoy having a warm place to stay for the winter and, for females, have their babies in spring. A hedgehog box allows hedgehogs to hibernate safely without being disturbed by other animals. When spring comes around, you can give them a plate of canned cat food.
Cut the wood into four equal pieces lengthwise with the saw. Nail the pieces together lengthwise. Leave the opening at about 4 inches square.
Saw a 4-inch by 6-inch hole near the base of the box.
Make a hole in the back end of the box, close to the top, big enough for the pipe to fit through, using the drill.
Insert the pipe in the hole. Make sure the pipe angles down coming out of the box to drain excess moisture.
Fasten two pieces of ¾-inch wood, long enough to cover the length of the box, to the bottom of the box. Nail them on from the inside.
Saw one end of the tunnel so it's angled enough to touch the ground when attached to the box.
Nail the tunnel on from the interior of the box.
Attach the roofing felt to the box to keep the hedgehogs warm and the weather out.
Put dry leaves or straw in the box until it's filled around two-thirds full.
Place the house in an undisturbed spot.
