Zoo worker (6)
I believe the answer is:
keeper
'zoo worker' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for keeper that I've seen before include "slips on my right hand usually" , "Animal custodian; plain ring" , "Zoo attendant" , "One at the wicket" , "Person or guard in charge or animals or people" .)
