Hedgehog Care: The Complete Guide to Keeping an African Pygmy Hedgehog Well

Good hedgehog care comes down to a short list of things done consistently: a warm, roomy, solid-floored home, a carefully measured diet, a quiet evening routine, and an exotic-animal vet you’ve found before you need one. The African pygmy hedgehog (Atelerix albiventris, the four-toed hedgehog sold as a pet across the US) is a small, nocturnal, solitary insectivore with a few needs that surprise new keepers. Their most common health problems also stay hidden until they’re advanced.

Below: whether a hedgehog is right for you (and legal where you live), the setup, temperature, diet, handling, health, and a routine. Where reputable veterinary sources disagree, we tell you so rather than picking a number and pretending it’s settled.

The short version: keep the room at roughly 75–80°F and never let it drift below the upper 60s. House one hedgehog per enclosure, with a large, solid-surface wheel. Feed a measured few teaspoons of a quality hedgehog or insectivore diet daily, not tablespoons. Weigh them weekly in grams. And book a checkup with an exotic-animal vet every 6–12 months.

Hedgehog care starts with an honest question: is this the right pet for you?

Hedgehogs are wonderful, quirky animals, and a real commitment. Here’s the clear-eyed picture.

They’re awake when you’re asleep

Good hedgehog care fits their schedule. The Merck Veterinary Manual describes four-toed hedgehogs as solitary and nocturnal. They sleep all day and run their wheel for hours after dark, so a bedroom enclosure will be heard.

One hedgehog, one enclosure

Hedgehogs don’t want a friend. The University of Florida’s veterinary hospital puts it bluntly in its hedgehog care handout: they “need to be housed alone,” and males in particular can fight seriously if housed together. Plan for one animal per enclosure, always.

A shorter life than most people expect

Lifespan figures for pet hedgehogs vary a lot online, so here’s where the veterinary sources actually land. Merck gives an average of 4–6 years. LafeberVet’s clinician reference lists a mean of 3–5 or 4–6 years depending on the source, with “up to 10y recorded.” UF says “approximately 6 years or more” with proper care. The “8–10 years” figures you’ll see on some care sites describe rare outliers, not what to plan around. Plan around 4–6, and budget for senior-year vet care.

Who shouldn’t keep one

Hedgehogs can carry Salmonella while looking perfectly healthy. Because of that, the CDC’s outbreak guidance says pet hedgehogs are not recommended for children under 5, adults 65 and older, or anyone with a weakened immune system. Handwashing handles the risk for most households, but if yours includes a toddler or someone immunocompromised, a hedgehog is the wrong choice right now, and that’s a caring decision, not a failure.

Is it legal to keep a hedgehog where you live?

Check this before you fall in love. Pet hedgehogs are legal in most of the US, but rules are set at the state and city level. These are the restrictions we confirmed against the regulations or the agencies that enforce them:

• California: prohibited. The state’s restricted-species regulation (14 CCR §671) lists hedgehogs under Order Insectivora, all species.
• Georgia: hedgehogs (Order Erinaceomorpha, all species) are on the state’s wild-animal list and require a license. Georgia issues those licenses for purposes like science, education, and exhibition, so in practice that rules out keeping one as a household pet.
• New York City: prohibited under the city Health Code (Article 161), which lists “mole and hedge hog” among banned insectivores. This is a city rule, not a New York State rule. Several care guides get this wrong.
• Pennsylvania: not allowed. A bill to legalize hedgehogs and sugar gliders, HB 692, was introduced in 2025. When we checked, it hadn’t moved out of committee, so the ban still stands.
• Hawaii and Washington, D.C.: both are widely reported as no-hedgehog jurisdictions. Hawaii’s Department of Agriculture has confiscated pet hedgehogs, and a 2018 attempt to add them to D.C.’s allowed-pets list was dropped. Confirm the current rule with the agency before buying.

Other states, counties, cities, and HOAs may require permits or have their own rules, and those change. Before you bring a hedgehog home, check with your state wildlife agency and your city or county animal control. Federally, the USDA licenses people who breed and sell hedgehogs, and hedgehogs can’t be imported from countries with foot-and-mouth disease. That’s part of why US pets come from domestic breeders. A hedgehog confiscated because its owner didn’t check is the one who pays for the mistake.

Where to get one

Look at rescues first. Hedgehogs do end up in rescues, often because their first owners didn’t expect the night-time noise or the vet bills. If you buy, choose a breeder who can tell you the parents’ ages and health history, will talk openly about Wobbly Hedgehog Syndrome in their lines, and handles their babies daily from a young age. A USDA license means the breeder is regulated. It doesn’t guarantee healthy animals: the hedgehogs in the CDC’s 2019 Salmonella outbreak came from USDA-licensed breeders, unlicensed breeders, pet stores, and online sellers alike. Never buy on impulse.

Setting up the enclosure: space, floor, wheel, and bedding

Floor space: bigger than the pet store suggests

Merck recommends a minimum floor area of 2 × 3 feet (about 0.6 × 0.9 m). UF’s handout suggests 4 × 2 feet. Treat 6 square feet as the floor, not the goal: hedgehogs travel a surprising distance in a night, and more room means more natural movement and less weight gain. Floor space matters far more than height. Tall multi-level cages add fall risk without useful room.

Two things to avoid. Wire floors can trap legs and tear off toenails; UF calls for “only solid bottom cages.” And while Merck says plastic-bottomed wire cages are fine if the bars are closely spaced, it warns that widely spaced wire “can result in limb entrapment or death.” Merck also advises against glass aquariums because they don’t ventilate well. Hedgehogs climb and escape, so secure the lid.

The wheel is not optional

Merck calls exercise wheels “highly recommended” and says they “should always be provided” for weight control. The rule that matters is the running surface: solid metal or plastic, never wire or rungs, because legs get trapped. Size it generously. UF suggests the giant wheels made for chinchillas. A common keeper rule of thumb is that your hedgehog should be able to run with its back flat, not arched. We haven’t found a veterinary source that specifies an exact diameter, so the honest guidance is “large and solid.” Hedgehogs often poop while running, so clean it most mornings.

Bedding and hides

Give them a hide (an igloo, a fleece sleeping bag, or a covered box) plus bedding deep enough to dig in. Merck suggests 3–4 inches (8–10 cm) in at least part of the enclosure. Recycled paper bedding is the safest choice. Merck also lists aspen shavings, alfalfa pellets, and hay as acceptable, and UF allows kiln-dried pine or aspen. Every source agrees on one point: no cedar, and nothing dusty or scented. Watch for loose threads in fleece liners and frayed fabric, because they can wrap around tiny toes.

Add tunnels, a dig box, and food scattered through the bedding. Merck notes foraging increases exercise.

Temperature, light, and torpor: the hedgehog care rule that matters most

Temperature is where a small hedgehog care mistake becomes an emergency. When African pygmy hedgehogs get too cold they can slip into torpor, a sluggish, hibernation-like shutdown. Merck describes it as “believed to be unhealthy”: it suppresses the immune system and can lead to organ problems or starvation.

The numbers, and why they don’t quite match

The veterinary references give slightly different ranges:

• Merck: 72–90°F acceptable, with 75–85°F optimal.
• LafeberVet: 75–85°F.
• UF: 70–80°F.

The thresholds for torpor also differ: Merck says it can be triggered below about 68°F (20°C), while LafeberVet says to add heat if the temperature falls below 65°F (18°C). The overlap is clear enough to act on. Aim for roughly 75–80°F at the hedgehog’s level, and treat anything in the upper 60s as a warning, not a normal winter night. Heat isn’t harmless either: Merck notes that very high temperatures can also cause torpor, and UF says to keep the enclosure out of direct sunlight.

How to heat safely

Merck suggests a heating pad placed under the enclosure or a ceramic heat emitter, the kind sold for reptiles. Run it through a thermostat, with a thermometer at floor level where the hedgehog sleeps. Keep the enclosure away from drafts, windows, and air-conditioning vents. Merck also recommends low humidity (under 40%) and about 12 hours of light a day.

If your hedgehog is cold, limp, or unresponsive

A hedgehog in torpor may feel cool to the touch on its belly, move slowly or wobble, and respond very little when handled. Move it somewhere warm right away. Warm it gradually against your body or in a warmed room, never on direct high heat. Then call your exotic-animal vet the same day. Merck notes that the outlook is usually good “once a quiet, warm environment is provided and fluid therapy administered,” and fluid therapy is something only your vet can give. A torpid hedgehog can also look a lot like one with neurological disease, so let the vet sort out which one you’re dealing with.

Hedgehog diet: how much to feed (teaspoons, not tablespoons)

Hedgehogs are insectivores, and in captivity they get fat easily, which makes portion control the core of hedgehog care. Merck calls obesity “very common in four-toed hedgehogs kept as pets,” and obese hedgehogs may also have fatty liver disease without showing signs. That’s where popular hedgehog care advice goes noticeably wrong.

The main diet

Merck recommends a commercial hedgehog or insectivore diet as the base. If one isn’t available, it suggests a high-quality weight-management cat food instead. LafeberVet gives a target of roughly 30–50% protein and 10–20% fat on a dry-matter basis. (that’s with moisture removed, so it won’t match the bag’s label directly).

The portion problem

Merck’s guidance is 3–4 teaspoons (15–20 mL) of the main diet per day, adjusted for the animal’s weight and activity. Several widely read care guides, including vet-clinic handouts that rank well in search, recommend 1 to 3 tablespoons instead. A tablespoon is three teaspoons, so 2–3 tablespoons is 6–9 teaspoons, roughly double to triple the vet-manual amount. For an animal where obesity is “very common,” that’s a big difference. Use a real measuring spoon, start in Merck’s range, and let the scale guide you.

The extras

On top of the main diet, Merck recommends a small daily supplement of:

• About 1–2 teaspoons of varied moist food (canned cat or dog food, cooked meat or egg) and/or gut-loaded insects such as crickets or dubia roaches. “Gut-loaded” means the insects were fed a nutritious diet before being offered, which is the same principle we explain in our leopard gecko care guide.
• About 1 teaspoon of a vegetable/fruit mix, such as cooked carrots, squash, peas, leafy greens, banana, apple, pear, or berries.

Go easy on fatty larvae. Merck lists “high-fat larval insects” among the first things to cut for an overweight hedgehog. LafeberVet suggests mealworms in small numbers (5–6 at a time, a few times a week) and says to avoid waxworms. Mealworms are a treat, not a meal.

Foods to skip

Merck says hedgehogs shouldn’t get raw meat or raw egg (because of Salmonella risk) or milk, which causes diarrhea. UF adds seeds, nuts, hard raw vegetables, dried fruit, avocado, onion, bread, honey, and junk food. There are a couple of disagreements worth knowing about. Merck includes grapes and tomatoes in its produce examples, while UF lists grapes, raisins, and tomatoes as foods to avoid. When one veterinary source flags a food and plenty of safe alternatives exist, the caring choice is simple: skip it. Nothing about your hedgehog’s health depends on grapes.

Weigh weekly, in grams

Merck recommends weighing hedgehogs weekly. A digital kitchen scale that reads in grams is one of the best tools you can own. Merck gives typical adult weights of about 300–400 g for females and 400–600 g for males, but individuals vary. Your hedgehog’s own steady baseline matters more than any chart. LafeberVet offers a quick body-condition check: a healthy hedgehog should be able to roll up completely without fat bulging out of the ball. Log it: a slow, steady drop is often the first sign of illness. If your hedgehog does need to lose weight, do it gradually and with your vet. Merck notes that crash diets in obese hedgehogs risk fatty liver.

Fresh water should always be available, in a heavy shallow dish or a bottle your hedgehog has proven it can use.

Handling, behavior, and what your hedgehog is telling you

Merck notes that “with patience, most hedgehogs learn to accept handling,” and that hedgehogs rarely bite.

How to pick one up

UF’s advice is simple: approach slowly and quietly, then scoop your hedgehog up with two cupped hands from underneath, where the fur is soft. If it rolls into a ball, just hold it calmly and wait. Most will unroll once they feel secure. Handle it every evening, a little at a time, when your hedgehog is awake. Merck notes that daily handling from a young age helps a hedgehog grow into a tame adult, so a well-socialized baby from a good breeder makes the job much easier. One method to avoid: putting a balled-up hedgehog in water to make it unroll. Merck calls it stressful and says it can affect the hedgehog’s body temperature.

Huffing, popping, and balling

A frightened hedgehog raises its quills, tucks its head, and huffs, a hissing noise broken up by little coughs and pops. If it’s really scared, it rolls into a tight ball, held shut by a powerful muscle under the skin, and can stay that way a long time. It’s a prey animal saying “too much, too fast,” not dislike. Slow down and try again.

Self-anointing: the frothy, contorting thing

Sooner or later, your hedgehog will meet a new smell, then chew at it, work up foamy saliva, and twist around to spread the froth onto its quills. This is called self-anointing. It’s completely normal. Some guides claim to know what it’s for, but Merck says plainly: “The purpose of this behavior is unknown.”

Quilling

Baby hedgehogs shed their first “nest spines” at about a month old. LafeberVet notes that permanent spines last up to 18 months and are replaced gradually, one at a time. Young hedgehogs are often grumpy for a few weeks during heavy quilling. Bald patches, crusting, or heavy flaking, on the other hand, aren’t normal quilling and need a vet’s look, because mites and ringworm are both common in this species.

Hedgehog health: what to watch for, and when to see your vet

Here’s why good hedgehog care leans so heavily on prevention. Merck notes that hedgehogs “often hide signs of illness” and recommends a full exam and baseline bloodwork every 6–12 months, usually under sedation, since most of an exam can’t be done on a balled-up hedgehog. LafeberVet recommends exams once or twice a year. Find an exotic-animal practice before you bring one home. This section is about recognizing problems, not treating them. Any of the signs below means a vet visit.

Cancer is common

Merck calls neoplasia (tumors) “extremely common” in pet hedgehogs and a major cause of death. A US post-mortem study found tumors in about half of hedgehogs examined, most malignant, and a 2018 Japanese review of 105 cases found neoplastic lesions in 60%, with three-quarters of those malignant and the female reproductive tract the most common site. Merck describes mouth cancer (oral squamous cell carcinoma) as “extremely common” too. Watch for lumps, weight loss, bleeding from the vulva or blood in the urine, facial swelling, loose teeth, or reluctance to eat hard food.

On spaying, the experts disagree. Merck says that because uterine disease is so common, preventive spaying “should be strongly considered.” LafeberVet’s reference says sterilization is “generally not necessary” for hedgehogs kept on their own. Both are reputable. It’s a genuine judgment call that depends on your hedgehog’s age and health and your vet’s comfort with anesthetizing small exotics. It’s worth asking about at your first checkup.

Wobbly Hedgehog Syndrome

Wobbly Hedgehog Syndrome (WHS) is a progressive neurological disease. It usually starts as a slight wobble or trouble balancing, then gradually leads to paralysis. It’s suspected to be inherited, and there’s no cure. Merck notes that treatments have been “attempted without success,” and VCA says plainly there is “no treatment or cure.” The numbers vary by study. LafeberVet cites roughly 10% of North American pet hedgehogs, while a 2023 JAVMA study of more than 1,400 hedgehogs found 3.3%, with signs starting at an average age of about 3 years. A cold, torpid hedgehog can also wobble, so check the temperature, then see your vet.

Skin, mites, and ringworm

Merck calls the mite Caparinia tripilis “very common” in pet hedgehogs. Signs include quill loss, flaky or crusty skin, and itching. Ringworm (a fungal skin infection, mostly Trichophyton) is common too, can be present without obvious signs, and can spread to people. Both need a vet’s diagnosis.

Teeth, nails, and the everyday stuff

Hedgehogs get tartar, gum disease, and periodontal problems. Unlike rabbits’ and rodents’ teeth, Merck notes that hedgehog teeth “do not grow continuously and should not be trimmed.” Nails need regular trimming. LafeberVet notes that many hedgehogs need light sedation for it, which is a good thing to bundle into a checkup. Other red flags: not eating for more than a day, diarrhea that persists, labored breathing, or a steady weight drop on your weekly log.

Salmonella, and the hygiene that keeps everyone safe

Hedgehogs can carry Salmonella without any sign of illness. The CDC has investigated repeated multistate outbreaks linked to pet hedgehogs: 54 people in 23 states in 2019 and 49 people in 25 states in 2020, 14 of them children under 5. The CDC’s advice is simple and worth making a house rule:

• Wash your hands right after handling your hedgehog, its food, or anything in its enclosure.
• Don’t kiss or snuggle your hedgehog against your face, and don’t eat or drink while handling it.
• Keep the hedgehog and its supplies out of the kitchen. Clean them outdoors when you can, and never where food is prepared.

Your hedgehog care routine: daily, weekly, and yearly

Once the setup is right, day-to-day hedgehog care is a manageable, lovely part of the evening.

Every day

• Measure out the main diet and the small extras, and check that yesterday’s food was eaten.
• Refresh water, and spot-clean the wheel, litter area, and any soiled bedding.
• Glance at the thermometer at floor level.
• Spend evening time handling and letting your hedgehog explore a safe, enclosed play area.

Every week

• Weigh in grams and log it.
• Do a full bedding change and wash the hides and fleece.
• Do a quick health check: eyes, quills, skin, feet, and nails, plus any lumps you can feel while handling.

Something you’ll notice fast: hedgehog people tend to become enthusiastic exotic-pet people. If your household also has a scaly resident, our Bearded Dragon Crown Sunglasses King T-Shirt is made for exactly that kind of keeper. It’s the first design in our Wear the Obsession line, and every species gets its turn.

Every 6–12 months

• A checkup with your exotic-animal vet, including baseline bloodwork, a dental check, and a nail trim if needed.
• Re-check your heating equipment and thermostat before winter, and your cooling plan before summer.

Hedgehog care FAQ

Can two hedgehogs live together?

No. Veterinary sources agree that hedgehogs are solitary and should be housed alone. Males in particular can fight seriously.

Do pet hedgehogs hibernate?

No, and the European hedgehog in British gardens is a different species. When a pet hedgehog gets cold, it goes into torpor, which is dangerous. Keep it warm, and call your vet if it ever becomes cool and unresponsive.

Why is my hedgehog foaming at the mouth and licking its quills?

That’s almost certainly self-anointing, a normal response to new smells. If the foaming happens with weakness, trouble breathing, not eating, or anything else unusual, call your vet.

Final thoughts on hedgehog care

The hedgehogs that thrive have a few things in common: a warm room, a big solid wheel, a measured spoon of food, a weekly weigh-in, and a keeper who knows an exotic vet by name. None of that is complicated. It just has to happen every day.

If you’ve read this far, you’re the kind of keeper hedgehogs do well with. The first evening your hedgehog unrolls in your hands and wanders up your sleeve is worth the wait.
