Companion Hedgehog Welfare: Activity Requirements and Common Health Problems

Hedgehogs are nocturnal insectivores with specific activity and dietary needs. Understanding their requirements prevents the common welfare failures affecting many companion hedgehogs.

Key Facts

African pygmy hedgehogs need to run several kilometers per night on a wheel for exercise
They are illegal to keep as pets in some US states and many countries
Wobbly hedgehog syndrome — a progressive neurological disease — affects many captive individuals
Obesity is common in hedgehogs fed inappropriate diets high in fruit and commercial cat food
Hedgehogs are solitary and suffer from social housing with other hedgehogs

Welfare Considerations

Companion hedgehog welfare is frequently compromised by inadequate space and activity opportunity. Wild hedgehogs travel up to 3 km per night foraging — captive hedgehogs deprived of equivalent activity develop obesity and behavioral abnormalities. A solid-floored wheel is essential, not optional. Wobbly hedgehog syndrome, a progressive and fatal neurological disease, has a genetic basis suggesting breeding population problems. Diet should primarily be high-protein insectivore food rather than cat food or fruit. Before acquiring a hedgehog, prospective owners must research requirements thoroughly and check local legality.

What You Can Do

Verify hedgehog legality in your jurisdiction before acquisition
Provide a large solid-floored exercise wheel and allow running every night
Feed an appropriate high-protein insectivore diet rather than cat food or fruit
Provide a large enclosure with hiding options and enrichment for this active species
