During hibernation hedgehogs are not really asleep, instead they drop their body temperature to match their surroundings and enter a state of torpor. This allows them to save a lot of energy but slows down all other bodily functions making normal activity impossible.

How long do hedgehogs hibernate for?

Hedgehogs usually hibernate from October/November through to March/April. Research has shown that each individual is likely to move nesting sites at least once during this period and so can sometimes be seen out and about. During mild winters hedgehogs can remain active well into November and December.

How does a hedgehog prepare for hibernation?

To prepare for true hibernation, hedgehogs spend the months before eating more and storing up fat. They may even prepare a nest for hibernation. By storing up food and slowing down their bodies, they can preserve energy and survive the winter months.
