A dormouse is a rodent of the family Gliridae (this family is also variously called Myoxidae or Muscardinidae by different taxonomists). Dormice are nocturnal animals found in Africa, Asia, and Europe. They are named for their long, dormant hibernation period of six months or longer. Dormice are small rodents, with body lengths between 6 and 19 cm (2.4 and 7.5 in), and weight between 15 and 180 g (0.53 and 6.35 oz). They are generally mouse-like in appearance, but with furred, rather than scaly, tails. They are largely arboreal, agile, and well adapted to climbing. Most species are nocturnal. Dormice have an excellent sense of hearing and signal each other with a variety of vocalisations. Dormice are omnivorous, and typically feed on berries, flowers, fruits, insects, and nuts. They are unique among rodents in that they lack a cecum, a part of the gut used in other species to ferment vegetable matter. Their dental formula is similar to that of squirrels, although they often lack premolars: (Source: Wikipedia.org, CC BY-SA)
