Overview

What is this animal?

African pygmy hedgehogs are small, nocturnal insectivores derived from the four-toed hedgehog.
They are covered in non-barbed spines they raise and curl into a ball when frightened.
Each animal has a distinct personality, from bold and explorative to shy and defensive.

They are solitary by nature and must be housed alone; cohabiting adults fight and become stressed.
They are often mis-sold as easy starter pets, but their heat, space, and dietary needs make them better for committed intermediate keepers.

Temperament

Hedgehogs are shy, independent, and naturally defensive, huffing and balling up until they learn to trust a keeper.
With patient, daily, gentle handling many become tolerant and curious, though they rarely seek affection like a dog or ferret.
They are most active at night.

They are not lap pets and dislike loud, busy environments.
Their quills can prick, so they suit calm, gentle handlers rather than young children.
Consistent routine and scent familiarity build the most confident animals.

A good fit for

Quiet, patient keepers wanting a solitary pet
Night owls who can interact in the evening
Owners able to provide steady warmth and space
People wanting a low-social-need exotic

Common mistakes to avoid

Housing two together (they fight and stress)
Letting temperatures drop and triggering hibernation
Overfeeding causing obesity and fatty liver
Wire or mesh floors injuring delicate feet

Enclosure

Minimum 5,000 cm² of floor (775 sq in) · 120 × 60 cm

Must be housed alone. Strictly solitary; house alone

Use a large enclosure with a solid floor and high sides, at least 0.5 square metres of floor space, such as a 120x60cm vivarium or large tub.
Avoid wire floors and mesh that can trap their legs.
Provide a deep, dust-free substrate such as fleece liners or paper-based bedding, a hide, and a large solid-surface running wheel.

Temperature is critical: maintain a stable 22-26C using a thermostat-controlled ceramic heat emitter or heat panel.
Cold hedgehogs may attempt hibernation, for which this species is not adapted and which is often fatal.
Provide a gentle day-night light cycle.

Diet

These animals lean strongly insectivorous and thrive on a high-protein, moderate-fat, low-filler diet.
A good base is a quality hedgehog kibble or high-protein grain-free cat food, supplemented with live or dried insects such as crickets, mealworms, and dubia roaches.

Feed measured portions at night, as obesity is common and dangerous.
Offer occasional small amounts of cooked egg or lean meat.
Avoid milk, bread, and sugary or salty human foods.
Provide fresh water in a shallow bowl or bottle.

Health

Common problems include obesity, dental disease, mites, and fatty liver from poor diet.
A serious neurological condition called Wobbly Hedgehog Syndrome causes progressive paralysis and has no cure.
Cancer is also relatively frequent in older animals.

Monitor weight, droppings, and gait closely, and find an exotic vet before you need one.
"Self-anointing," where a hedgehog froths and spreads saliva over its spines in response to new smells, is normal behavior, not illness.

Is this urgent?

Small mammals are prey animals. They mask pain and illness by instinct, so by the time something is obvious it is usually already advanced.

Go now

Not eating, or eating far less than normalCall an exotics vet. Bring a recent weight if you have one. In a hindgut fermenter the gut slows and then stops when food stops moving through it. This is the single most common emergency in small mammals.

8 hours

No droppings, or droppings suddenly tiny, misshapen or scarceCall an exotics vet now. Take a photo of the litter tray. Output is the most reliable read on gut movement there is, and it fails before the animal looks unwell.

8-12 hours

Sitting hunched, pressed to the floor, unwilling to moveGo now. A hunched, still posture in a prey animal is a pain posture.

Now

Audible teeth grinding or crunchingGo now. Soft tooth purring is contentment. Loud, slow grinding is pain.

Now

Hard, bloated or drum-tight abdomenGo now. Do not offer food or attempt to massage the abdomen. Gas or an obstruction can become fatal within hours and needs imaging, not home care.

Now

Laboured breathing, open-mouth breathing, or clickingGo now. Keep the animal cool and undisturbed in transit. Most small mammals are obligate nose breathers; open-mouth breathing means they are already struggling.

Now

Maggots or fly eggs anywhere on the animal, especially the rearGo now. Do not attempt to wash them off first. Flystrike can kill within a day. Risk rises sharply in warm weather and in any animal with a dirty or damp rear.

Now

Today

Head tilted persistently to one side, or circlingBook today. Several causes, most of which respond far better to early treatment.

Today

Weight down 5 percent or more since the last weighingCall today, and bring the weight history. Weight falls before appetite visibly changes. This is why weekly weighing is worth the two minutes.

Today

Soon

Drooling, wet chin, or dropping food while trying to eatBook a dental check. Continuously-growing teeth can overgrow into the tongue or cheek long before the animal stops trying to eat.

A few days

Scratching hard enough to break skin, or bald patches spreadingBook an appointment. Mites and fungal infections spread, and some transfer to other animals in the household.

A few days

Have the number of an exotics-competent practice saved before you need it. Most general small-animal clinics do not treat rabbits or rodents out of hours, and finding one at 11pm is not realistic.

This is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.

Can a african pygmy hedgehog eat that?

Most small companion mammals are hindgut fermenters: the gut is a fermentation vessel that has to keep moving, and sudden rich food stops it.

RhubarbVery high in soluble oxalate, high enough to cause acute kidney injury. The leaves are worse than the stalks.

never

Salty or seasoned human foodSalt, oil and seasoning. Crisps, chips, seasoned leftovers and processed meat are all out.

never

SweetcornThe hulls are indigestible and are a recognised blockage risk in small herbivores.

never

Rare treats (13)

AppleSugar. The seeds contain a cyanogenic compound and must be removed. A thin slice, once or twice a week. Never the seeds or core.

rare treat

BananaVery high in sugar and starch, and most animals will overeat it given the chance. A slice the width of a fingernail, rarely.

rare treat

BlueberrySugar, but a small portion size makes it easy to control. One or two berries, twice a week.

rare treat

Brussels sproutsHighly gas-forming. Half a sprout, rarely.

rare treat

CarrotSold as the archetypal rabbit food and it is nothing of the kind: carrot is a root vegetable with a high sugar content. The leafy tops, by contrast, are an excellent green. A thin slice as a treat. The tops can be fed freely.

rare treat

CauliflowerOne of the most gas-forming brassicas. A very small piece, occasionally.

rare treat

GrapesVery high in sugar. Halve them, because a whole grape is a choking hazard. One halved grape, rarely.

rare treat

OrangeAcidic and sugary; can irritate the mouth and gut. A tiny segment, rarely if at all.

rare treat

PearSugar. Remove the seeds. A thin slice occasionally.

rare treat

PeasHigh in starch and sugar. The pods and leaves are better than the peas. A few pods occasionally.

rare treat

StrawberrySugar, though lower than most fruit. The leaves are actually the better part. Half a small berry, once or twice a week.

rare treat

TomatoThe ripe flesh is safe in small amounts. The leaves, stems and any green fruit contain solanine and must never be offered. A small piece of ripe flesh, occasionally. Never the plant.

rare treat

WatermelonSugar and a very high water content, which together can loosen the gut. Remove the seeds. A small cube in hot weather, rarely.

rare treat

Occasional (17)

BasilSafe and well liked. Rotate rather than relying on it. A few leaves.

occasional

Bok choyGood green, mildly goitrogenic like other brassicas. A leaf or two a few times a week.

occasional

BroccoliNutritious but a notable gas producer. Leaves and stalk are better tolerated than the florets. A small floret or a piece of stalk, twice a week.

occasional

CabbageA brassica. Gas-forming in quantity, and goitrogenic with heavy long-term feeding. A small piece, once or twice a week.

occasional

CelerySafe and well liked. Cut across the stalk so the long fibres cannot catch. A short piece, cut into segments.

occasional

ChardSame oxalate issue as spinach. A small leaf, occasionally.

occasional

CourgetteSafe and mild. Serve raw. A few slices a few times a week.

occasional

CucumberSafe, but it is mostly water with very little in it. Useful for hydration in warm weather, poor as a staple. A few slices.

occasional

DillSafe in rotation. A few fronds.

occasional

Green beansSafe cooked or raw in small amounts. Gas-forming in quantity. One or two, occasionally.

occasional

KaleHigh in calcium and a mild goitrogen. Genuinely nutritious, but not the everyday green it is often sold as. A leaf or two, two or three times a week.

occasional

MintSafe in small amounts; strongly flavoured and not every animal wants it. A leaf or two.

occasional

ParsleyNutritious but relatively high in calcium. Fine in rotation, not as the whole green portion. A few sprigs, a few times a week.

occasional

PumpkinSafe and well tolerated in small amounts. A small cube occasionally.

occasional

RocketPeppery and well tolerated in rotation. A small handful, a few times a week.

occasional

SpinachHigh in oxalates, which bind calcium and contribute to bladder sludge and stones in animals prone to them. A single small leaf, no more than once or twice a week.

occasional

WatercressNutritious, strongly flavoured, high in calcium. A small handful occasionally.

Everyday foods (6)

Bell pepperOne of the best everyday vegetables here: high in vitamin C, low in sugar, no oxalate problem. Remove the seeds and stalk. A few strips daily.

everyday food

Carrot topsThe leaves are a proper green and much better food than the root. A handful as part of the daily greens.

everyday food

CorianderWell tolerated, aromatic, and most animals take it readily. Part of a daily mixed handful.

everyday food

Dandelion leavesOne of the best greens available, and free. Pick well away from roadsides and anywhere that may have been sprayed. A generous handful daily.

everyday food

Grass hayShould be about 80 percent of what this animal eats, available at all times. It is what wears the teeth down and what keeps the gut moving. Unlimited, always.

everyday food

Romaine lettuceDark leafy lettuce with real nutritional content and a good water balance. A generous handful daily as part of a mixed selection.

everyday food

That food is not on our list. Do not offer it on a guess — check with an exotics vet, or leave it out. Nothing in a small mammal's diet is urgent enough to risk it.

Introduce any new food one at a time, in a small amount, and wait two days before adding another. A change in droppings is the earliest signal that something did not suit.

Buying the setup

Bedding and substrate

Bedding has three jobs: absorb, stay dust-free, and let the animal dig. Anything aromatic is failing the second one.

Safe

Dust-extracted paper beddingThe default for almost every small mammal. Look for 'dust extracted' on the label rather than 'natural'.

safe

Kiln-dried aspen shavingsThe one wood that is fine, because it has no aromatic phenols. Kiln-dried matters.

safe

Hemp beddingVery absorbent and low dust. More expensive per litre but goes further.

safe

Soft meadow hay as a top layerFood and bedding at once for rabbits, guinea pigs and chinchillas. Never the only absorbent layer.

safe

Plain shredded paper or paper stripsUnprinted or soy-ink only. Cheap nesting material; poor as the main absorbent layer.

safe

Fleece liners over an absorbent layerOnly works with an absorbent layer underneath and a wash every few days. Fleece alone holds urine against the skin.

safe

With a caveat

Cardboard-based beddingFine, but it goes soggy quickly and needs changing more often than paper.

with a caveat

Sand bathsCorrect and important for chinchillas, degus and gerbils. Use plain chinchilla bathing sand, never 'dust' products and never builder's sand.

with a caveat

Hemp or straw pelletsGood absorbency, but too hard to burrow in. Use under a soft layer, not as the whole substrate.

with a caveat

Never

Pine and cedar shavingsThe aromatic phenols that make them smell pleasant are the problem: they damage the liver and kidneys and the cells lining the airway. Laboratory work found liver enzyme changes in mice after roughly a day of cedar exposure, taking well over a week away from it to settle, and enlarged livers in mice kept on pine for months.

never

Raw corncobTwo separate problems. It is swallowed and causes intestinal blockage, and it grows mould readily once damp.

never

Cotton wool and fluffy nesting materialSold as bedding, and it wraps around limbs and is swallowed. Repeatedly implicated in amputations in hamsters.

never

Scented or perfumed bedding of any kindAdded fragrance is an airway irritant in an animal whose nose is centimetres from the bedding all day.

never

Clumping cat litterSwallowed during grooming, and it clumps just as effectively inside the animal.

never

SawdustDust plus, usually, softwood. Both problems at once.

never

This is our general list for small pets. We have not built one specific to Hedgehogs yet.

Depth matters as much as material for burrowing species. A hamster needs 25 cm or more of substrate it can actually tunnel through; shallow bedding on a large floor is still an inadequate enclosure.
