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