A local zoo has a “taxidermy department” and noteworthy animals are preserved or skinned and the skins sold to friends of the zoo.
Its kept very secret because it would be publicly unpopular. A friends dad has a mountain lion skin because he is a contractor who does a lot of work for the zoo and did a few jobs for them that NEEDED to be done basically for cost when they were suffering some financial troubles. They gave him the pelt as a Xmas present.
Google “Knee sleeves” literally designed for the purpose.
