I'm a little stuck... Click here to teach me more about this clue!

'fur' is the definition.
(I've seen this before)

I don't understand the rest of the clue.

(Other definitions for ocelot that I've seen before include "Type of American wildcat" , "Wildcat -- loo etc (anag)" , "South and Central American wildcat" , "Leopard-like cat of S America" , "American cat, like a small leopard" .)

I've seen this clue in The Telegraph.
