Top 10 Fascinating Facts About Hedgehogs

There are 17 different hedgehog species living across Europe, Africa, and Asia. In the UK, they adapt to various habitats—from woodlands and farmlands to city parks and private gardens. These adaptable creatures thrive in urban areas, frequently making homes in cemeteries, along railways, and in green spaces where food and shelter are available.

They Are Widespread and Sociable

Night Owls That Avoid the Heat

Hedgehogs are nocturnal and spend most of the day sleeping. During winter, they hibernate in nests built from leaves, usually from November to mid-March. They become active again in spring, but only after sunset.

They Are Lactose Intolerant

A common myth suggests hedgehogs drink milk directly from cows, leading many to leave milk out for them. However, hedgehogs cannot digest lactose. Instead, they benefit more from wet cat food or specially formulated hedgehog food available at garden centers.

Carnivorous Appetites

Despite their small and charming appearance, hedgehogs are efficient predators. Their diet includes worms, slugs, insects, beetles, and occasionally small frogs, bird eggs, snakes, and fruit.

Poor Eyesight but Sharp Senses

Hedgehogs have weak vision, but they compensate with an excellent sense of hearing and a strong sense of smell, helping them navigate and find food in the dark.

Skilled Runners, Climbers, and Swimmers

These small mammals are surprisingly athletic—they can run, climb, and even swim when necessary, making them adaptable to various terrains.

Surprisingly Speedy

For short distances, hedgehogs can reach speeds up to 9.5 km/h (about 5 mph), allowing them to escape danger or hunt efficiently.

Size and Spines

An adult hedgehog typically measures 20–25 cm in length and weighs around 1.2 kg. Their backs are covered with roughly 5,000 to 7,000 short, sharp spines—which are actually modified hairs—while their face and underside are fur-covered. They also have a small, often overlooked tail.

Facing Serious Decline

Hedgehog populations in the UK have significantly decreased, with numbers estimated to have dropped by over half in rural areas and one-third in urban environments since the year 2000.

Many Die from Human-Related Causes

Although hedgehogs can live two to three years on average, many perish prematurely due to road accidents, lawnmowers, garden strimmers, and exposure to chemicals.
