Prickly beastie once branded witch now at sharp end of habitat threats
Is it true that hedgehogs rely on hearing and sense of smell because they have poor eyesight?
Not really. As creatures of the night, their senses of smell, taste and hearing are highly attuned. When you prowl around in pitch darkness, a smell or sound will catch your attention where a visual cue will fail.
But it’s not true that hedgehogs have poor eyesight – the fact is that hedgehogs don’t use their eyes because they don’t need to.
Tell us some interesting and largely unknown facts about hedgehogs.
Did you know they’re lactose intolerant? Or that they can run really fast in short bursts – up to 9km per hour? They’re also good swimmers and climbers.
What do hedgehogs eat? Is it true they are allergic to cheese?
It’s definitely not good for them. Hedgehogs are lactose intolerant (see above) so milk or cheese are a no-no. As for what they do like, hedgehogs are noisy, enthusiastic eaters. Like greedy toddlers, they eat with deliciously few table manners – plenty of crunching, open-mouthed slurping and lip-smacking going on with every meal. They’re generalists, surviving on a diet consisting largely of insects. This unfussy palate serves hedgehogs well: not only will they devour slugs, earwigs, beetles and worms with relish, but they can also stomach caterpillars and millipedes which, to other species, taste bitter or unpleasant.
How do they communicate?
On the whole, hedgehogs are solitary animals, so for most of the year they don’t need to communicate with each other.
However, come mating season it’s a whole different story. When a male finds a female, he knows he must impress her. A “dance” ensues, he circles her endlessly, snorting and grunting, trying to win her over.
Famous hedgehogs?
Lots – they pop up all over literature, from Shakespeare to the Bible, Philip Larkin to Beatrix Potter.
What is the lifespan of a hedgehog?
Three to seven years in the wild but the oldest lived to the ripe old age of 15, in captivity in Germany.
Are they declining in numbers? Is there anything we can do to preserve them?
Yes, sadly it’s true. In the 1950s it’s estimated that there were around 30 million hedgehogs in the UK. Now, we’re down to less than a million. That’s why I wrote the book, to give practical advice on how to help them: everything from making wild corners in your garden to putting out food, making hedgehog houses to checking bonfires.
