To monitor humidity levels, you can use a hygrometer, which is a device that measures moisture in the air. If you find that the humidity in your hedgehog's habitat is too low, consider using a humidifier or placing a shallow dish of water in the enclosure to help increase moisture levels. Conversely, if the humidity is too high, ensure proper ventilation and avoid over-watering any plants you may have in the habitat.
Additionally, providing a warm area for your hedgehog to burrow and hide can help them regulate their body moisture. Always ensure that the habitat is clean and dry to prevent any mold or mildew, which can thrive in high humidity environments.
