Collection of animals (9)
I believe the answer is:
menagerie
'collection of animals' is the definition.
(a menagerie is a collection of animals)
This is all the clue.
(Other definitions for menagerie that I've seen before include "A collection of wild animals in captivity" , "Wild animal collection" , "Beastly lot" , "where the occupants behave like animals" , "Animal exhibition" .)
