Do hedgehogs hibernate?
The answer is yes they do, although they do not hibernate continuously throughout winter every few days they get up to find food. Putting food out during the winter can be a life saver (literally) for hedgehogs, but don’t out out tinned food like tinned cat or dog food as it will freeze! And if you can put water out regularly otherwise this will freeze too.
Hedgehogs traditionally begin hibernation between October and November, however due to climate change hedgehogs are starting hibernation later and later. Some even begin in January as that is the coldest period of winter.
Did you know that during hibernation a hedgehogs body temperature drops to 1-5 degrees, compared to their normal foraging temperature of 34 degrees.
What weight do they have to get up to?
Adult hedgehogs should be at least 500 – 700g. This ensures they have enough fat to keep them going throughout the winter. Despite their regular forages food in Winter is very scarce and so they must put a lot of weight during the plentiful summer to make up for it.
Why do hedgehogs Hibernate?
Hibernation saves energy. As I have already mentioned food is scarce in the winter and if hedgehogs were as active as they are in the summer they would use more energy foraging than the energy given to them by eating food. Therefore to stay in a good energy balance hedgehogs only eat every few days.
Where do hedgehogs hibernate?
Pretty much anywhere in your garden: under a shed, in a compost heap, under piles of brambles of logs, or they might choose a bonfire. This is why you should always check your bonfire before lighting it as this is one way hedgehog numbers have severely reduced.
