The Angora rabbit (Turkish: Ankara tavşanı) is a variety of domestic rabbit bred for its long, soft wool. The Angora is one of the oldest types of domestic rabbit, originating in Ankara (historically known as Angora), Turkey, along with the Angora cat and Angora goat. The rabbits were popular pets with French royalty in the mid-18th century, and spread to other parts of Europe by the end of the century. They first appeared in the United States in the early 20th century.As with all rabbits, abundant and unlimited hay should be provided. The fiber the rabbit gains from the hay helps prevent wool block (also referred to as intestinal impaction). It is also recommended particularly for Angora and other long-haired rabbit species that any pellet diets have at least 13% fiber. Fiber content can be found in the nutritional analysis on the food bag. Additionally fecal impaction can be caused by dehydration, which can be prevented by providing unlimited water as well as a salt lick to encourage drinking water.
