Hedgehog Enrichment: A Survey of Owners Found What Most Are Missing
In a survey of pygmy hedgehog owners, 84 percent had no hide, 68 percent housed them under half a square metre, and 17 percent provided no wheel. That is the checklist.

Hedgehog Enrichment: A Survey of Owners Found What Most Are Missing
Most guides in this series start with an experiment. This one starts with a survey of what hedgehog owners actually provide, which turns out to be more useful. For everything else about them, see our complete Hedgehog care guide.
In a 2024 assessment of pygmy hedgehog owner practice, 84 percent of animals had no hiding house, 68 percent were housed in under half a square metre, and 17 percent had no wheel. Those three numbers are the enrichment priority list for this species, in reverse order of how often they get skipped.
What the Research Actually Says
The relevant work is an assessment of owner investment in African pygmy hedgehog welfare across feeding, housing, enrichment, hygiene and health practice, published in the Journal of Veterinary Behavior in 2024. Owners were grouped by where they got their care information: a vet, other owners and breeders, or the internet.
The housing and enrichment findings are blunt. 84 percent lacked a hide. 68 percent were in enclosures under 0.5 square metres. 17 percent had no wheel. Owners who consulted a vet were more likely to clean the wheel daily, which matters more than it sounds for an animal that defecates while running.
The natural history sits alongside it: wild hedgehogs routinely travel five kilometres or more in a night foraging. No pet enclosure delivers that, which is why the wheel is not a toy.
The information-source split is the quietly damning part of that study. Where an owner got their advice predicted what the animal actually had, which is a reasonable argument for care guides taking themselves seriously.
The Wheel
The highest-value item and the one closest to a requirement. A large solid-surface wheel is the only realistic substitute for a night's foraging distance.
Solid running surface, not mesh or rungs, because hedgehog feet and legs are easily damaged by grid. Large enough that the animal runs with a straight back rather than an arched one. And clean it daily, since they run and defecate at the same time and the mess is not optional.
A hedgehog that uses its wheel heavily every night is doing the thing this species most needs to do.
A Hide, Which 84 Percent Do Not Have
The most commonly missing item on the list and one of the cheapest to fix. Nocturnal animals that sleep through the day need somewhere dark and enclosed to do it.
A hideout plus fleece liners or a snuggle sack gives somewhere to burrow into. Hedgehogs push under fabric and sleep buried, and giving them nothing to burrow under leaves a nocturnal animal sleeping in the open.
Check fleece for loose threads, which can wrap around toes. That is a common and preventable injury.
Floor Space, Well Past Half a Square Metre
The second-most-missed item. Half a square metre is small for an animal built to cover kilometres, and floor area matters more than height here since hedgehogs are poor climbers and can be injured falling.
Long and wide rather than tall, with a solid floor. Our tank setup guide covers dimensions and why ramps and levels need care in this species.
Warmth, Which Is a Welfare Emergency If Missed
Not enrichment exactly, and it belongs on the list because everything else fails without it. African pygmy hedgehogs need consistent ambient warmth, and a cold hedgehog may attempt hibernation, which for this species in captivity is dangerous and often fatal.
A ceramic heat emitter on a thermostat holds the ambient temperature without adding light to a nocturnal animal's night. Our health issues guide covers attempted hibernation and what to do about it.
Foraging
Insectivores that hunt across ground. Scatter feeding, insects released into a dig box of safe substrate, and food hidden inside cardboard or under objects all turn a bowl into a search.
Live insects are the strongest version. Watch the weight either way, since obesity is common in pet hedgehogs and a wheel plus scatter feeding addresses both halves of it. Our feeding guide covers the diet.
Alone, Deliberately
Unlike almost every other small mammal in this series, this species is solitary. Adults housed together fight, and solo housing is correct rather than a compromise.
Priority Order
- A large solid-surface wheel, cleaned daily
- A hide with something to burrow under
- Floor space well beyond half a square metre
- Consistent ambient warmth on a thermostat
- Scatter and dig-box foraging with live insects
- Solo housing
- Novel objects and rearrangement, last
What Not to Do
Do not skip the wheel, which 17 percent of owners in that survey did. Do not leave a nocturnal animal without a hide. Do not use a mesh or open-rung wheel. Do not use unsealed fleece with loose threads. Do not let the enclosure get cold enough to trigger hibernation attempts. Do not house two adults together. And see our handling guide before assuming a huffing, balled-up hedgehog is going to enjoy being socialised on your schedule, and our legal guide, since they are banned outright in several places.

❓ Frequently Asked Questions
Is there research on hedgehog welfare?
There is a 2024 study assessing owner investment in African pygmy hedgehog welfare across feeding, housing, enrichment, hygiene and health practice. It is a survey of what owners actually do rather than an enrichment experiment, and what it found is a useful list of common gaps.
What were the main gaps it found?
84 percent of hedgehogs had no hiding house, 68 percent were housed in under half a square metre, and 17 percent had no wheel. Owners who had consulted a vet were more likely to wash the wheel daily.
Is a wheel really essential?
It is the closest thing to essential in this species. Wild hedgehogs routinely cover five kilometres or more in a night foraging, and no pet enclosure provides that distance. A wheel is the only realistic substitute for that much locomotion.
What kind of wheel?
Large, solid-surface and with a solid running track rather than mesh or rungs. Hedgehog feet and legs are easily injured by grid surfaces, and a wheel too small forces the spine into a curve. Expect to clean it daily, because they defecate while running.
Do hedgehogs need heat?
Yes, and it is the most commonly missed requirement. They need consistent ambient warmth, and if they get too cold they can attempt hibernation, which is dangerous for a captive African pygmy hedgehog and can be fatal.
Should hedgehogs be kept together?
No. African pygmy hedgehogs are solitary and adults kept together fight. Unlike most small mammals in this series, solo housing is the correct answer for this species rather than a compromise.
