Eliomys quercinus
A dormouse with a black band from nose to behind the ear that looks like spectacles or a mask, and a long tail ending in a black-and-white tuft. Nocturnal and the most carnivorous dormouse, it hibernates for up to seven months.
The garden dormouse (Eliomys quercinus) is a rodent of the dormouse family found from Europe to North Africa and western Asia. Despite its name it lives in many habitats: forests, rock crevices, hollow trees, steppe and even houses. The back is grey to brown and the belly white or cream, and its key feature is a black band running from the nose through the eye to behind the ear, which also separates it from the hazel dormouse and others. The long, bushy tail is brown, black and white in European animals. It is nocturnal and lives both in trees and on the ground, sometimes taking over bird or squirrel nests. It is the most carnivorous dormouse, eating insects, snails, small mammals and nestlings as well as fruit, nuts, acorns and eggs. It hibernates for up to seven months, sleeping so deeply it can be rolled over without waking. It is in a different genus from the African pygmy dormouse already kept in Japan, where it appears only occasionally at specialists.

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.

Omnivore, the most carnivorous dormouse: insects, snails, fruit and nuts
Active both in trees and on the ground. Use a tall cage with branches and a nest box, plus ground-level hides, and fine mesh, as it slips through small gaps.
The most carnivorous dormouse, eating many insects and snails. Always include animal food such as insects, alongside fruit and nuts.
Nocturnal, sleeping deeply by day. It can share feeding and sleeping sites, but may fight in the breeding season.
It hibernates for up to seven months, with daytime sleep lengthening from about October. 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 has declined in parts of its native range and has almost vanished from the Netherlands. It is in a different genus from the African pygmy dormouse, and captive information is limited. Never release captive animals into the wild.
