West Mexican margay (a pair) were in a small (way too small) cage across from the old elephant exhibit, which is where they are currently doing the paid close encounters (or were last I was there).
Amur leopard cat was in Cat Canyon in the small carnivore cages on opposite side of road from the big cats.
Mongolian Wolf was in Cat Canyon in one of the big cat cages.
Persian and North China leopards were in the bottom two of the big cat cages (though later the last North China leopard was at the top in the newer glass fronted case that held serval last time I was there).
Gordon's or Arabian wildcat has been at various places, including some former small cages below Cat Canyon (across from pandas) and even (way out of place) in Polar Bear Plunge in the pine marten exhibit (or whatever is in there now).
Royal antelope were in a small enclosure behind the former tree kangaroo exhibit.
