Glis glis
The largest dormouse, grey above and white below with a bushy tail, rather squirrel-like. A nocturnal tree dweller that eats beech mast and acorns and hibernates from autumn to spring.
The edible or fat dormouse (Glis glis) is the largest member of the dormouse family. It ranges over most of Europe and parts of western Asia, south to Italy and northern Turkey, north to Latvia, west to northern Spain and east to western Russia and northern Iran, with populations on Mediterranean islands and in Britain. It prefers deciduous and mixed forest rich in mast trees such as beech and oak, avoids conifer forest, and also uses caves, tree holes and houses. It is nocturnal and arboreal, resting by day in nests or tree holes. It uses all three kinds of dormancy, daily torpor, hibernation and aestivation, and is a true hibernator, spending autumn to spring in an underground chamber living on body fat. Beech mast, acorns and hazelnuts are its main foods, with much fruit in summer plus flowers, leaves, insects and fungi. Wild animals live about 9 years on average and up to 12; the captive average is 8.7. In Japan it is rare, reaching specialists only once every several years, and is in a different genus from the African pygmy dormouse.

Not covered by CITES, the Invasive Alien Species Act or the specified-animal rules. Imports fall under Japan's animal import notification system (Infectious Diseases Control Law, MHLW): a health certificate from the exporting country's government must be filed with the quarantine station, and rodents must come from a holding facility designated by that government. Animals bred in Japan can be sold and kept without notification. Never release captive animals into the wild.

Mainly herbivorous omnivore: beech mast, acorns, hazelnuts and fruit
Nocturnal and arboreal, resting in tree holes or nests by day. Provide a tall cage with branches and a nest box placed high.
Staples are beech mast, acorns and hazelnuts, with lots of fruit in summer; it also eats flowers, leaves, insects and fungi, so do not feed nuts alone.
Mostly solitary, though close relatives may share nests or hibernate together.
It uses daily torpor, hibernation and aestivation, hibernating underground from autumn to spring. Wild dormice fatten in autumn and hibernate for months. Hibernation can kill a weak captive animal, so decide with an exotic-animal vet in advance whether to allow it and how to manage winter temperatures.
Imports fall under the animal import notification system; animals bred in Japan need no notification.
It can live close to 10 years, and as it is rarely traded, husbandry information is limited. Never release captive animals into the wild.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
