Musky "cat" (5)
I believe the answer is:
civet
'musky cat' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for civet that I've seen before include "A very expensive coffee is made from its poop" , "Cat; scent" , "fur" , "Smelly nocturnal cat-like mammal with a barred and spotted coat" , "Wild cat; perfume" .)
