Well, I can say that stroking Gaur is an experience. As a zoochatter that doesn't like ignorant, annoying people doing this kind of thing, I do feel maybe I should have left it, but I REALLY couldn't resist, and the Gaur didn't seem to mind.
What I will say though, is if you try this have some hand sanitizer - luckily we did, because they leave a sort of oily, dirty residue.
