Hedgehog Welfare: Wild and Companion Animals

Wild hedgehogs face population decline across Europe, while African pygmy hedgehogs kept as pets have complex welfare needs that are frequently unmet. Both populations deserve greater attention.

Key Facts

The European hedgehog (Erinaceus europaeus) has declined by up to 75% in some UK rural areas since the 1950s
Wild hedgehogs travel 1–3 km per night foraging; they are solitary, nocturnal, and hibernate in winter
The African pygmy hedgehog (Atelerix albiventris) is the most commonly kept pet hedgehog species
Captive hedgehogs require exercise wheels, varied insect-based diet, and nocturnal environments — needs often poorly met
Hedgehogs are prone to Wobbly Hedgehog Syndrome (WHS), a progressive neurological condition with a genetic component
In the U.S., African pygmy hedgehogs are banned in several states including California, Hawaii, and Georgia

Welfare Considerations

Wild hedgehog welfare is primarily threatened by habitat fragmentation — removal of hedgerows, garden fencing, and slug pellet use has devastated populations. Urban hedgehogs face road mortality, entanglement in garden netting, and secondary poisoning from pest control products. For pet hedgehogs, welfare failures are common: nocturnal animals kept in brightly lit rooms, fed inappropriate diets, and denied adequate exercise space develop obesity, foot sores, and psychological problems. Hedgehogs are not naturally social animals — attempting to keep them in pairs causes stress. Welfare for captive hedgehogs requires nocturnal lighting cycles, insect-supplemented diet, large wheel for exercise, and hiding structures. Wild hedgehog welfare can be improved through garden-friendly design and predator management.

What You Can Do

Create a hedgehog highway — cut a 13cm gap in garden fencing to allow wild hedgehog movement
Avoid slug pellets and ensure garden netting is raised off the ground to prevent entanglement
If keeping a pet hedgehog, provide a large wheel, varied insect diet, and nocturnal environment
Support the British Hedgehog Preservation Society and People's Trust for Endangered Species
Check compost heaps and bonfires for hibernating hedgehogs before disturbing them
