a small animal with long ears and soft fur, that lives in a hole in the ground.——朗文当代大辞典

A gregarious, burrowing, plant-eating mammal, Oryctolagus cuniculus (family Leporidae, order Lagomorpha), which has long ears, typically brownish-grey fur, and a short, white tail, has been domesticated and bred as a pet and for meat, and is proverbial for its rate of reproduction. Originally: †a young rabbit (the adult being called a coney) (obsolete). In recent use more fully European rabbit. Also with distinguishing word specifying the breed.——牛津当代大辞典  @en
