Howdy X,
I went out there a while ago, very interesting place, but it's not photographer friendly. I don't mean this as a slam, but the animals are the main concern and they don't do anyting that will allow them to be upset. A lot of the animals there are from "Rescues" and other breeding programs that have failed, and so as soon as one of the cats becomes a little nervous, the Guide moves everyone on. It is a nice place to go see a very wide selection of Big Cat's, and some very rare ones, but due to the containment areas they are very difficult to get through the wires and other obstacles for decent shots at least for me anyway

.
I highly recommend it as a place to visit, but if your wanting shots of Big Cats from what I have seen you will not be offered the type of shooting experience as PugMug.
