A Self-Built Winter Den for Hedgehogs

Building a Winter Den for Hedgehogs

Hedgehogs are increasingly threatened, partly due to declining insect populations, which limits their ability to gain sufficient weight for winter hibernation. Providing a safe winter den can help them survive the colder months.

Constructing the Den

A simple den can be constructed from a cardboard box.

• Materials: A sturdy cardboard box.
• Preparation: Remove the top lid of the box. Turn the box upside down.
• Entrance Hole: Cut an entrance opening of 9 x 9 cm (approximately 3.5 x 3.5 inches) in the middle of one long side. This specific size is crucial to prevent larger animals like cats or dogs from entering.
• Waterproofing: Cover the exterior of the cardboard box with air foil (bubble wrap) to make it waterproof and windproof. Secure the foil with staples.
• Insulation: Fill the interior of the den with dry leaves to provide insulation.

Den Placement

Place the filled hedgehog den in a quiet, sheltered spot, such as near a hedge. Position the entrance facing south-east for weather protection. Place the den within a pile of leaves and cover it with a few wooden branches to prevent the leaves from being blown away by the wind.

Supporting Weakened Hedgehogs

For hedgehogs that appear weak, it is advisable to provide supplemental food and water.

• Important: Never offer milk, as it causes diarrhea in hedgehogs.
• Suitable Foods:
  • Dry hedgehog food
  • Canned cat food
  • Cooked eggs
  • Banana
  • Unsalted, fried minced beef

Hedgehogs naturally feed on slugs, spiders, and other insects.
