Most rabbits have soft fur consisting of a dense undercoat and slightly longer guard hairs.
Most rabbits have erect ears, which can be as short as 2 inches in dwarf breeds. Lop rabbits have ears that hang down and include the longest-eared of all rabbits, the English lop who's ears can span nearly 3 feet. Rabbits live an average of about six years. However, with good care, a life span of 10 years is not unusual. Rabbits are quiet and relatively inexpensive to house and maintain.
