Not all hedgehogs hibernate, and the ability to do so largely depends on the species and environmental conditions. In the wild, European hedgehogs (Erinaceus europaeus) are known to hibernate during the colder months when food is scarce. They typically find a safe, dry place to curl up and enter a state of torpor, which can last for weeks or months, depending on the temperature and availability of food.

On the other hand, African pygmy hedgehogs (Atelerix albiventris), which are more commonly kept as pets, do not hibernate in the same way. They may go through periods of lethargy or sleep more during colder months, but this is not true hibernation. Instead, they require a stable environment with consistent temperatures and should be kept indoors, away from extreme cold.

If you own a hedgehog, it's important to monitor their behavior and environment, ensuring they have a comfortable habitat that meets their needs throughout the year. If you notice any unusual behavior during colder months, it's a good idea to consult with a veterinarian who specializes in exotic pets.

In summary, while European hedgehogs can hibernate, African pygmy hedgehogs do not hibernate in the same way and require different care.
