Hedgehogs are quiet, compact, and full of personality, but they are not low-maintenance pets. They are nocturnal insectivores with strict temperature needs, and the most common new-owner mistakes, a cold room and a wire-floor cage, are entirely preventable. This guide covers the four pillars of hedgehog care: housing, temperature, diet, and handling.
Setting Up the Enclosure
Giving a hedgehog the right home starts with floor space and safety. Aim for at least 2 by 3 feet of floor area, with more being better, and always a solid floor since wire bottoms injure tiny feet. Good ventilation matters, so glass aquariums are a poor choice compared to open-top plastic cages or converted storage bins.
- Bedding: paper-based bedding, fleece liners, or kiln-dried aspen. Never cedar, and avoid strong-smelling pine.
- Hideout: a dark enclosed igloo, PVC tube, or snuggle sack where the hedgehog feels safe by day.
- Wheel: a solid-surface running wheel is essential; hedgehogs walk several miles a night, and wire or mesh wheels cause injuries.
- Water: a heavy ceramic bowl or a sipper bottle, refreshed daily.
Temperature Is a Lifesaving Rule
Wild hedgehogs hibernate, but a captive hedgehog that tries to hibernate enters a dangerous state called torpor that can be fatal. Keep the enclosure between 72 and 80 degrees Fahrenheit (22 to 27 Celsius) at all times, measured with an actual thermometer rather than guesswork. A ceramic heat emitter with a thermostat is the standard solution. If you ever find your hedgehog cold, wobbly, and unresponsive, warm it gradually against your body and contact an exotic vet immediately. Do not wait to see if it snaps out of it.
Feeding an Insectivore
Hedgehogs need a high-protein, low-fat diet built around quality hedgehog or cat kibble, topped up with insects. Fat hedgehogs look adorable but obesity shortens their lives.
| Food | How often | Notes |
|---|---|---|
| High-protein, low-fat kibble | Daily base | About 1 to 2 tablespoons per night |
| Mealworms or crickets | 3 to 4 times weekly | 5 to 10 as a protein treat |
| Cooked plain chicken | Occasional | Unseasoned, small pieces |
| Soft vegetables | Small amounts | Cooked sweet potato, peas, carrot |
Avoid dairy, chocolate, grapes, raisins, avocado, onion, nuts, seeds, and anything sugary. Hedgehogs are lactose intolerant, so no milk saucers despite the old storybook image.
Handling, Taming, and Nightly Enrichment
Hedgehogs are solitary and shy. Handle them in the evening when they wake, let them sniff your hands first, and scoop from underneath with both hands rather than grabbing from above. Hissing, puffing, and balling up are stress signals, so slow down and be patient. With gentle daily handling for two to four weeks, most hedgehogs relax noticeably, especially if you offer a mealworm during sessions. One quirky behavior to expect: self-anointing, where a hedgehog foams saliva onto its quills after smelling something new. It looks alarming but is completely normal. Expect a lifespan of 4 to 6 years, and line up an exotic-animal vet early, since hedgehogs hide illness well. Meet these basics and your prickly little roommate will thrive.
