Forest feline (4)
I believe the answer is:
lynx
'forest feline' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lynx that I've seen before include "Animal that's spotted" , "Wild cat -- text browser" , "Wild cat noted for keen sight" , "Sharp-eyed cat" , "Wild cat with yellowish-brown fur and tufted ears" .)
