African pygmy dormouse
Graphiurus murinus · also called Woodland dormouse, African dwarf dormouse, African dormouse, Micro squirrel, APD
A tiny, fast, highly arboreal African rodent kept in social colonies; an entertaining display species that is too quick and delicate for handling and needs warm, tall, escape-proof housing.

Part of the Dormice
Small arboreal rodents of the family Gliridae, characterized by bushy tails, large eyes, nocturnal habits, and a tendency toward torpor in cool conditions. The pet-kept species are fast, delicate display animals that need tall, warm, escape-proof homes.
Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Habitat & enclosure
African pygmy dormice are arboreal and need a tall, very secure enclosure: a large glass terrarium or fine-mesh vivarium oriented vertically, with extremely small gaps because these tiny rodents can squeeze through and chew out of weak enclosures. Fill the space densely with branches, cork bark, ropes, foliage (real or artificial), and multiple nest boxes or hides high up, plus a deep substrate layer for occasional digging and a wheel suited to small rodents. The emphasis is on climbing volume rather than floor area.
They are sensitive to cold and will enter torpor if chilled, so maintain a warm temperature, generally around 21-25 C, with a gentle ambient heat source if the room is cool, and moderate humidity. Keep the enclosure out of drafts and direct sun. No UVB is required, but the warmth, height, dense cover, and absolute escape-proofing are essential because escaped APDs are extremely hard to recover.
Substrate
Use a deep layer (10cm+) of aspen, hemp, or paper-based bedding mixed with dry leaf litter and moss to allow burrowing and foraging. Avoid dusty or aromatic softwood shavings like cedar and pine. A layer of sphagnum moss in one corner helps hold the moderate humidity these arboreal mice prefer.
Equipment & setup
Keep them in a tall, very escape-proof glass terrarium with fine mesh (they squeeze through cage bars and chew plastic) and lots of branches, cork tubes, and live or fake foliage for climbing. Maintain 21-25C ambient with a low-wattage heat source if your room is cool, and provide a small solid-surface or mesh-free wheel. They are highly social and must be kept in same-sex pairs or small groups, never alone.
Diet
African pygmy dormice are omnivores with a strong insectivorous and nectar component. Offer a varied diet built on appropriately sized live or dried insects (small crickets, mealworms, etc.) plus a quality small-rodent or insectivore mix, supplemented with small amounts of fruit, and a nectar/pollen-type supplement or suitable sweet sap substitute to mirror their natural intake.
Rotate foods to keep the diet varied and provide gut-loaded insects for nutrition. Supply fresh water (a shallow dish or bottle they can reach in the canopy) and dust insects with a calcium/vitamin supplement to support bone health. Avoid relying on seed-heavy mixes alone.
Behavior & temperament
These dormice are nocturnal, lightning-fast, and almost constantly climbing and leaping; they are best appreciated as a watch-don't-handle species, since they are extremely difficult to hold and can be lost or injured in an instant. They are skittish but fascinating to observe, especially their acrobatics through branches at night.
Unlike many small rodents, they are social and generally kept in colonies; many keepers report that larger, stable groups are more active, vocal, and entertaining, while lone animals do poorly. Introduce animals carefully and provide plenty of hides and feeding stations to reduce conflict. Enrich heavily with climbing structures, foraging for scattered insects, and varied canopy furniture.
Health
Common issues stem from husbandry: chilling leads to torpor and stress, so stable warmth is critical, and obesity or malnutrition can result from an unbalanced (too sweet or too seed-heavy) diet. Their tiny size makes injuries from falls, escapes, or rough handling a real risk, and their incisors grow continuously so chew material is needed.
Monitor for weight loss, lethargy, wet or soiled fur, and signs of dehydration, and use an exotics vet experienced with very small mammals. As prey animals they hide illness well, and their speed makes catch-up and examination difficult, so prevention through correct temperature, diet, and secure housing is the best medicine.
Tips, DIY & hacks
Offer foraging enrichment by scattering small insects (mealworms, crickets), seeds, and bits of fruit through the leaf litter to mimic natural foraging. Provide nest boxes or coconut hides with tissue for communal sleeping, and mist lightly in the evening. They are tiny, fast, and nocturnal escape artists, so do all maintenance over a bin or in a closed room.
