'African' Leopard at Paradise WP, 01/09/13

Spot pattern make me think perhaps there was some crossbreeding with jaguar somewhere in its lineage.

Yes, I noticed that. The breezy generalisation about spots within rosettes is not invariably diagnostic. Sometime in the mid 90s London held a male Persian Leopard, bred at Bristol, that had similar markings, although the background coloration was much paler.
