### Materials Needed:
1. **Wooden Box or Plastic Container**: Use untreated wood or a sturdy plastic container that is at least 30 cm (12 inches) wide, 45 cm (18 inches) long, and 30 cm (12 inches) tall.
2. **Wooden Planks or Plywood**: For the base and walls of the shelter.
3. **Straw or Hay**: For bedding, which provides insulation and comfort.
4. **Non-toxic Sealant**: If using wood, ensure it's treated with a non-toxic sealant to protect it from the elements.
5. **Tools**: Saw, nails or screws, hammer or screwdriver, and possibly a drill.
### Instructions:
1. **Choose a Location**: Find a quiet, sheltered spot in your garden, away from direct sunlight and harsh winds. A corner of the garden or near hedges is ideal.
2. **Construct the Shelter**:
- **Base**: Cut the wooden planks or plywood to create a solid base. This will prevent moisture from seeping in.
- **Walls**: Cut four pieces for the walls, ensuring they fit securely onto the base. The walls should be tall enough to provide shelter but not too high to make access difficult.
- **Roof**: Create a slanted roof to prevent rain from pooling on top. Ensure it can be lifted off for cleaning.
- **Entrance**: Cut a small entrance (about 10 cm x 10 cm) on one side. This should be low enough for hedgehogs to enter easily but not so large that it exposes them to predators.
3. **Insulation**: If you’re in a colder climate, consider adding insulation between the walls. You can use straw or hay to line the inside of the shelter, which will help keep it warm.
4. **Weatherproofing**: If using wood, apply a non-toxic sealant to the exterior to protect it from moisture. Ensure that any screws or nails are not protruding, as these can harm the hedgehogs.
5. **Finishing Touches**: Place the shelter on the ground, slightly elevated if possible, to avoid flooding during rain. Add a layer of straw or hay inside for bedding.
6. **Maintain the Shelter**: Regularly check the shelter for signs of use and clean it out at least once a month, replacing the bedding as needed.
### Additional Tips:
- Avoid using cedar or pine shavings for bedding, as these can be harmful to hedgehogs.
- If you want to attract wild hedgehogs, consider adding a feeding station nearby with hedgehog food or cat food.
- Make sure the shelter is secure and predator-proof to keep the hedgehogs safe.
By following these steps, you can create a cozy and safe shelter for hedgehogs, helping them thrive in your garden or providing a comfortable home for your pet hedgehog.
