Rabbits are small mammals in the family Leporidae. The male is called a buck and the female is a doe; a young rabbit is a kitten or kit. Rabbit habitats include meadows, woods and grasslands. The rabbit’s long ears, which can be more than 10 cm (4 in) long, are probably an adaptation for detecting predators. They have large, powerful hind legs. The two front paws have 5 toes, the extra called the dewclaw. The hind feet have 4 toes.
