Short-tailed feline (4)
I believe the answer is:
lynx
'short-tailed feline' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lynx that I've seen before include "Animal that's spotted" , "Wild cat; sounds like chain" , "Wild cat with yellowish-brown fur and tufted ears" , "Keen-eyed cat" , "Keen-eyed feline" .)
