I would go with Richard Stell because he use to have a serval, which is an african wildcat the size of a german shepard and use to go work at a big cat refuge. He is one of those guys who knows animals inside and out, it's because of him I started collecting taxidermy so that I could really study animals and see how they work. I never did get a full body panther from him just a panther/rose/eagle morph about a decade ago, never to late until I run out of room though.
