Leopard. Several pictures below. The hardest of the "Big 5" to find on safari but spend enough time, you should eventually see many. The above and below sighting was absolutely perfect right at sunset. It was a male and female mating.

This leopard had a kill up in a tree. Not a great set of pics, but still a cool sighting. Below are 3 other shots are also from this sighting. That's an impala it's eating.
Kruger National Park - South Africa May - 2008







This leopard showed up at a waterhole just as two black rhino were leaving. Not a great picture because it was at night but still nice to see these species together.
