Fur is a synonym for hair, used in reference to non-human animals, usually mammals, particularly those with extensive body hair coverage. The term is sometimes used to refer to the body hair of an animal as a complete coat, also known as the "pelage". Fur is also used to refer to animal pelts which have been processed into leather with the hair still attached, as is the custom in the making of fur coats in certain fashion trends. The words fur or furry are also used, more casually, to refer to hair-like growths or formations; particularly when the subject being referred to exhibits a dense coat of fine, soft "hairs."
Animal fur, if layered, rather than grown as a single coat, may consist of short ground hair, long guard hair, and, in some cases, medium awn hair. Mammals with reduced amounts of fur are often called "naked", as in The Naked Ape, naked mole rat, and naked dogs.
An animal with commercially valuable fur is known within the fur industry as a furbearer. The use of fur as clothing and/or decoration is considered controversial by some people: most animal rights advocates object to the trapping and killing of wildlife, and to the confinement and killing of animals on fur farms.
Fur has been a major challenge for 3D computer graphics artists due to its visual complexity and physical properties. The first movie which made extensive use of CGI fur was Pixar's 2001 film Monsters, Inc..
Sheep (Ovis aries) are quadrupedal, ruminant mammals typically kept as livestock. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Although the name "sheep" applies to many species in the genus Ovis, in everyday usage it almost always refers to Ovis aries. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep.
Sheep are most likely descended from the wild mouflon of Europe and Asia. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleece, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. Ovine meat is called lamb when from younger animals and mutton when from older ones. Sheep continue to be important for wool and meat today, and are also occasionally raised for pelts, as dairy animals, or as model organisms for science.
Sheep husbandry is practised throughout the majority of the inhabited world, and has been fundamental to many civilizations. In the modern era, Australia, New Zealand, the southern and central South American nations, and the British Isles are most closely associated with sheep production.
