1. **Materials**: Use safe, non-toxic materials. Cardboard tubes (like those from paper towels or toilet paper), PVC pipes, or even wooden tunnels can work well. Avoid anything with sharp edges or toxic substances.
2. **Size**: Ensure the tunnel is wide enough for your hedgehog to move comfortably. A diameter of about 4-6 inches is usually suitable.
3. **Length**: Make the tunnel long enough to provide an engaging experience. A length of 2-3 feet can be ideal, but you can create a series of connected tunnels for added fun.
4. **Ventilation**: Ensure there are enough openings or holes for ventilation. This will help prevent your hedgehog from feeling trapped and keep the air fresh.
5. **Stability**: If you're using lightweight materials like cardboard, make sure the tunnel is stable and won't collapse when your hedgehog crawls through it. You can reinforce it with some tape or glue.
6. **Decorate**: Consider adding some soft bedding or shredded paper inside the tunnel to make it more inviting and comfortable.
7. **Supervision**: Always supervise your hedgehog while they are exploring the tunnel, especially if it's their first time using it. This will ensure their safety and help you gauge their interest.
8. **Cleanliness**: Keep the tunnel clean by regularly checking for any waste or debris and replacing any soiled materials.
Creating a DIY tunnel can be a fun project for you and a great enrichment activity for your hedgehog!
