Place to set free skunk (7)
I believe the answer is:
polecat
'skunk' is the definition.
('polecat' can be a synonym of 'skunk')
'place to set free' is the wordplay.
'set free' indicates anagramming the letters.
'place'+'to'='placeto'
'placeto' is an anagram of 'POLECAT'.
(Other definitions for polecat that I've seen before include "Weasel-like creature" , "Beast of weasel family" , "Beast related to weasel" , "Smelly American mammal" , "weaselly type" .)
