Wild animal’s home (4)
I believe the answer is:
lair
'wild animal's home' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lair that I've seen before include "Wild animal's place of refuge" , "Hiding place, den" , "Habitation of a wild animal" , "Rail around animal's den" , "animal refuge" .)
