1. **Paper-based Bedding**: Products like Carefresh or other paper-based bedding are excellent choices. They are absorbent, dust-free, and provide good airflow, which helps keep the environment cool.
2. **Aspen Shavings**: Aspen shavings are a great alternative to cedar or pine shavings, as they are less aromatic and safer for hedgehogs. They also allow for good ventilation and do not retain heat as much as some other bedding materials.
3. **Fleece Liners**: Using fleece liners can be a comfortable option for hedgehogs. They are washable, reusable, and can be kept cool by placing them in the freezer for a short period before use. Just ensure to change them frequently to maintain hygiene.
4. **Hemp Bedding**: Hemp bedding is another great option as it is highly absorbent, biodegradable, and provides good insulation while allowing airflow.
5. **Avoid Heat-retaining Materials**: Steer clear of materials like straw, hay, or any bedding that can trap heat. These can make the enclosure too warm for your hedgehog.
Make sure to monitor the temperature of your hedgehog's habitat regularly and provide plenty of fresh water and shade to help them stay cool during hot weather.
