Hedgehogs hibernating?

Hedgehog Hibernation: the facts

What is hibernation?

Hedgehogs are one of the few mammals that are true hibernators. 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.

Where might hedgehogs hibernate?

Hedgehogs aren’t fussy. A log pile, under your shed, in a compost heap or manmade hedgehog house can all provide a safe place for hedgehogs to nest in over winter.

Do hedgehogs sleep the whole time?

Hedgehogs will be relatively inactive over winter, especially when temperatures drop very low. However, on milder days it is possible that hedgehogs can wake up early and look for a quick bite to eat before returning to slumber.  Research also shows that during the hibernation period, hedgehogs can move between nests every few weeks, and even use nests built by other ‘hogs.

So what should I do while hedgehogs are hibernating?

It’s not necessary to put food out over winter as it will more than likely go to waste with hedgehogs hibernating. However, we do recommend providing water all year round.  On very mild days, or when you notice hedgehog activity in your garden, you may want to put some food out for a short time until it gets cold again.  Just make sure to never disturb a nesting hedgehog, so avoid opening up the hedgehog house or clearing the garden or leaf or log piles as they may have some sleeping ‘hogs inside!

Who should I call if I am worried about a hedgehog?

If you are ever worried about the health or welfare of a hedgehog, please call the British Hedgehog Preservation Society on 01584 890801 and they will be able to give you advice, and put you in touch with a local rescue centre if necessary.

I hope this helps to answer some of your hibernation questions!

Best wishes,

P.S. Having a bonfire? Always remember to check it for hedgehogs before burning! Or better still, re-site pile on day it’s to be lit, light from one side only to allow escape route for anything you may have missed!

Have you got a hedgehog highway?

Hedgehogs can travel up to a mile in just one night so our fences are getting in their way. Make a Hedeghog Highway today and log it on the BIG Hedgehog Map so we can find out where hedgehogs are going.
