American wildcat (6)
I believe the answer is:
ocelot
'american wildcat' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ocelot that I've seen before include "Spotted New World feline" , "American cat, like a small leopard" , "Leopard-like cat of S America" , "Feline of South and Central America" , "Yellow-black striped and spotted cat" .)
