Hedgehog Enclosure Setup: Temperature Is the Non-Negotiable Part

Hedgehog housing is fairly straightforward once you understand one hard rule: this species cannot tolerate a cold enclosure, and getting temperature wrong isn't a minor mistake, it's dangerous.

Enclosure Size

A minimum of 4 square feet of solid floor space, and bigger is fine as long as you fill roughly three-quarters of it with hides and enrichment items. Hedgehogs are prey animals and don't do well feeling exposed in a large, open space. C&C cages, large plastic bins, and guinea-pig-style cages, like a solid-bottom small animal home, all work well. The floor must be solid, never wire. Wire flooring catches limbs and causes real injuries.

Temperature: The Requirement That Overrides Everything Else

Keep the enclosure at 75 to 80°F, ideally, with a workable range of 72 to 90°F. Below about 72°F, hedgehogs can attempt to hibernate, a dangerous, potentially fatal response in a species not built to survive it safely in captivity.

A heat source, typically a ceramic heat emitter on a thermostat, is necessary for nearly every keeper, very few homes stay consistently warm enough without one. Avoid light-emitting heat bulbs specifically, they disrupt the day and night cycle and can contribute to triggering hibernation attempts, a lightless emitter is the safer choice on both counts.

Pair that with a digital thermometer so you're confirming the enclosure is actually staying inside that range rather than guessing.

This is also where hedgehogs part ways from the "small mammal" label they're often filed under. Their strict heat requirements have more in common with a sulcata tortoise's than with a hamster's or guinea pig's, worth keeping in mind if you're setting up more than one enclosure at once.

Humidity

Keep it on the low side, under 40% is preferred. If your home runs very dry, below about 30%, a humidifier bringing the room to 40 to 60% helps prevent itchy, flaky skin. The same digital thermometer/hygrometer combo covering temperature typically tracks humidity too, worth getting one that does both.

Substrate

Recycled paper bedding, aspen shavings, or fleece liners all work well, with 3 to 4 inches of depth in areas where your hedgehog can burrow. Avoid rough, dusty, or scented bedding, and skip anything with loose fibers or frayed fabric, both can trap toes and limbs.

Lighting

Keep light dim, this is a nocturnal species, and maintain a consistent 12-hour light and dark cycle. Bright, constant lighting is genuinely disruptive here, not just a minor annoyance.

The Non-Obvious Requirement: A Real Wheel

A large, solid-surface exercise wheel, 10.5 to 12 inches in diameter, like an axle-free running wheel, is essential, not optional. Avoid wire or mesh wheels entirely, they cause serious foot and leg injuries.

Rounding Out the Enclosure

A hideout, a water bottle, and a food dish complete a basic setup. None of it needs to be elaborate, but the temperature and the wheel genuinely aren't areas to cut corners on.
