A small European rodent of the genus Myoxus, of several species. They live in trees and feed on nuts, acorns, etc.; -- so called because they are usually torpid in winter.
Dormice are mostly found in Europe, although some species live in Africa or Asia. A nocturnal animal, dormice are particularly known for their long periods of hibernation.
