African Pygmy Hedgehog

About the species

The African pygmy hedgehog (Atelerix albiventris), also called the four-toed hedgehog, is a small insectivorous mammal native to dry, open habitats of central and eastern Africa. Only captive-bred animals should be kept as pets. According to the Merck Veterinary Manual, adult males weigh 400–600 g and females 300–400 g, and a relaxed animal measures roughly 18–23 cm. It is a nocturnal loner that needs constant warmth and an owner prepared to work around an evening routine.

Not the same as the hedgehog in your garden

The wild hedgehog that visits gardens is a different species and does not belong indoors. In Slovenia, the western European hedgehog (Erinaceus europaeus) and the white-breasted hedgehog (listed in the original decree as Erinaceus concolor) appear in Annex 1 of the Decree on Protected Wild Animal Species (Official Gazette RS No. 46/04, as amended), whose Article 13 prohibits keeping live animals of those species taken from the wild. The European hedgehog is also noticeably heavier – adults weigh 800–1200 g – and hibernates in winter, whereas a pet African pygmy hedgehog must not be allowed to slip into torpor.

Warmth is a requirement, not a comfort

An African pygmy hedgehog needs a steadily warm environment: the Merck Veterinary Manual gives an acceptable range of 22–32 °C, with 24–29 °C as optimal. The Royal Veterinary College (RVC) recommends 24–30 °C and placing the enclosure out of direct sunlight. A hedgehog that is too cold or too warm can go into torpor, a state considered unhealthy for this species. In a European winter that means a heated room or a safely controlled heat source with a thermometer inside the enclosure, not simply a room that is "usually warm".

A loner that covers a lot of ground at night

Every adult hedgehog must be housed alone. The RSPCA warns that two hedgehogs kept together are likely to fight, and young hedgehogs can reach sexual maturity at just 2–3 months, so they need to be separated by sex in good time. During the day the hedgehog sleeps and should not be woken; it becomes active in the evening and at night, when a wild animal may travel several kilometres while foraging. For the owner, that means contact mostly in the evening and plenty of opportunity for exercise.

Enclosure and wheel

The Merck Veterinary Manual recommends a floor area of at least 0.6 × 0.9 m, and the RVC advises the largest enclosure you can provide. Wire floors are unsuitable because they injure the feet. The exercise wheel needs a solid metal or plastic running surface, as legs can become trapped in wire wheels. Recycled paper bedding or aspen shavings work well, and the enclosure should include at least one hide for sleeping and room to explore. The RSPCA notes that hedgehogs are often kept in cages too small for such an active species.

Feeding without excess calories

The African pygmy hedgehog is an omnivore that feeds mainly on invertebrates in the wild. The Merck Veterinary Manual recommends a commercial hedgehog or insectivore kibble as the base of the diet, supplemented with gut-loaded insects and a smaller share of vegetables and fruit. Raw meat and eggs are avoided because of the risk of Salmonella infection. Obesity is common in captive hedgehogs, so the RVC advises measured portions, feeding in the evening and removing uneaten food in the morning.

Health: what is worth monitoring

Tumours are very common in this species: the MSD Veterinary Manual lists neoplasia as a major cause of death, and in one survey more than 80% of reported tumours were malignant. Wobbly hedgehog syndrome may also occur – a progressive neurological disease of unknown cause that usually begins with an unsteady gait in the hind legs and for which no treatment has so far proved successful. Other common problems include skin mites (Caparinia tripilis), fungal skin infections that can pass to people, dental disease, and heart muscle disease, which typically affects hedgehogs aged three years or older. Because hedgehogs can carry Salmonella, washing your hands after handling is a sensible habit. The RVC recommends a yearly check-up with an exotics vet, as problems are easier to manage when caught early.

Spines, rolling up and self-anointing

Most African pygmy hedgehogs roll into a tight ball when handled, so getting one used to your hands takes time; the RVC notes that hedgehogs handled from a young age adapt better. A distinctive trait of the species is self-anointing: when it meets a new smell or taste, the hedgehog produces frothy saliva and spreads it over its spines. This is natural behaviour and not in itself a sign of illness.

Who it suits

The African pygmy hedgehog suits an adult owner who can provide constant warmth, a spacious enclosure, a controlled diet and access to an exotics vet. According to the Merck Veterinary Manual the usual lifespan is 4–6 years, and some individuals live longer. The RSPCA considers that its needs are hard to meet in a typical household and that veterinary care can be expensive. It is not suitable for young children, as it sleeps during the day, rolls into a prickly ball when stressed and needs a quiet space. Check local regulations before buying, as ownership of exotic animals is restricted in some places.
