Fur clothing left their original pattern and color. Fur may be shorn down to imitate the feel of velvet, creating a fabric called shearling. Common animal sources for fur clothing and fur trimmed accessories include fox, rabbit, mink, raccoon dogs, muskrat, beaver, stoat (ermine), otter, sable, seals, cats, dogs, coyotes, wolves, chinchilla, and opossum and common brushtail possum. Some of these are more highly prized than others, and there are many grades and colors. In Europe and Asia, cheap and plentiful dog and cat fur is sold under different names to disguise the origin from shoppers in the United States, such as
European pine marten and the use of inhabited buildings for denning. Martens may also be affected by woodland loss. Persecution (illegal poisoning and shooting) by gamekeepers, loss of habitat leading to fragmentation, and other human disturbances have caused a considerable decline in the pine marten population. They are also prized for their very fine fur in some areas. In the United Kingdom, European pine martens and their dens are offered full protection under the Wildlife and Countryside Act 1981 and the Environmental Protection Act 1990. In Great Britain, the species was for many years common only in northwestern Scotland. A study in 2012
