=== Selección artificial ===
Humans have artificially selected some domesticated mammalian species to have breeds that are hairless. There are several breeds of hairless cats, perhaps the most commonly known being the [[Sphynx (cat)|Sphynx cat]]. Similarly, there are several breeds of [[hairless dog]]s. Other examples of artificially selected hairless animals include the [[Skinny pig|hairless guinea-pig]], [[nude mouse]], and the [[Fancy rat#Hairless rat|hairless rat]].

In clothing, fur is usually leather with the hair retained for its aesthetic and insulating properties. Fur has long served as a source of clothing for hominoids including the [[Neanderthal]]. Animal furs used in garments and trim may be dyed bright colors or to mimic exotic animal patterns, or shorn down to imitate the feel of a soft [[velvet]] fabric. The term "a fur" is often used to refer to a fur coat, wrap, or shawl.
