When I was a docent we had one in our education program. Unfortunately it was one of the few education animals that docents could not handle themselves (it had to be a keeper). However we had a nice setup of a large acrylic container on wheels with a divider in the middle. A keeper could put the polecat in one side for us and we could put a domestic ferret in the other side and wheel it out to show visitors the difference between the wild and domestic forms.

They weren't doing a very good job of it then, given this isn't the wild form of a ferret it's not even within the same genus, nor all that closely related. Marbled Polecat are actually sister to grisons and zorillas!
