Ferret-legging

[snopes]

Comment: Ferret-legging, allegedly a 'sport' involving sticking ferrets
down ones pants and cinching them up tight, was reported in an article
twenty years ago. The article, published by Donald Katz in the October
'87 issue of Outside magazine, was riddled with factual errors about
Ferrets that apologists attribute to "poor research on an actual sport."

The Wikipedia article on Ferret Legging, like most sources of information
on the pastime, has no direct sources except for Katz's article. It has
been nominated for deletion twice; both times, the votes were split
fifty/fifty and the article was kept.

Did Katz write a poor article on an actual sport, or did he make it up?
