Lesser Hedgehog Tenrec

About the species

The lesser hedgehog tenrec is one of the few exotic mammals kept in Slovenia by specialised exotic-pet breeders rather than found in ordinary pet shops. It is small, spiny and active at night, so its care has more in common with keeping a terrarium animal than a conventional household pet.

Before you get one

Not a hedgehog

The lesser hedgehog tenrec and true hedgehogs share a spiny coat and a broadly similar body shape at first glance, but they are entirely separate lineages of mammal, not even distant relatives. True hedgehogs – such as the African pygmy hedgehog, already featured on Živalce.si – belong to the order Eulipotyphla, while tenrecs belong to Afrosoricida, part of the larger Afrotheria group, making them more closely related to elephants, manatees and golden moles than to any hedgehog. The spiny look shared by both groups is a case of convergent evolution: two unrelated branches of mammals independently arrived at the same solution – spines as a defence against predators. Compared with a true hedgehog, the lesser hedgehog tenrec has a shorter snout, larger, rounder ears and finer, greyish-brown spines.

Size and appearance

An adult lesser hedgehog tenrec measures roughly 14 to 18 cm in body length and weighs between 110 and 230 g; according to the Smithsonian's National Zoo, females tend to run slightly larger than males. The back and flanks are covered in sharp spines ranging from yellowish to almost black, while the belly and muzzle are bare or only lightly furred. The tail is very short and barely visible, and the legs are relatively long and well suited to climbing.

Nocturnal life and clicking

The species is strongly nocturnal and solitary, sleeping curled up by day in a hollow tree, among roots or in a crevice, then foraging on the ground and among branches at night, where it climbs well. Researchers have also studied an unusual behaviour: the tenrec produces short clicks with its tongue and lips that are thought to help it find its way in the dark – a simpler analogue of the echolocation used by some bats. In the cooler months it can enter torpor, so a stable enclosure temperature matters: a sudden drop can trigger torpor outside the normal season.

Diet

The lesser hedgehog tenrec is an insectivore. The bulk of the diet is live crickets, roaches, mealworms and waxworms, with keepers occasionally offering cooked egg, unsweetened fruit or a pinky mouse. Because the diet is so specialised, regular vitamin and mineral supplementation is recommended, and the menu should stay varied enough that the animal does not become fixated on a single protein source.

Housing and care

A single tenrec needs a roomy terrarium or vivarium with deep substrate for digging and hiding, plus several hides and branches for climbing. Temperature should stay stable at roughly 22–27°C and humidity at 50–60%, which makes a thermostat and hygrometer worthwhile. The footprint needed is modest compared with a dog or cat, so the species can suit a smaller flat – but care depends on consistent temperature, humidity and diet, not just floor space.

Reproduction

Mating follows the tenrec's emergence from winter torpor, and gestation lasts roughly 60 to 68 days. Litters are relatively large for such a small animal, typically 5 to 7 young, with breeders occasionally reporting as many as 9.

Is it right for you?

The lesser hedgehog tenrec is not a beginner's pet. It needs stable terrarium conditions, a specialised diet and, above all, a vet experienced with exotic mammals – few of those practise in Slovenia or Croatia, so it is worth checking what is available before committing. Because of its spines and nocturnal schedule, it does not suit young children or frequent cuddling, but it makes an engaging, active animal for an experienced exotic-pet keeper drawn to species that are not yet common on Živalce.si.
