Animal hunt (6)
I believe the answer is:
ferret
I believe this clue is a double definition.
'animal' is the first definition.
(I've seen this before)
'hunt' is the second definition.
(I know that ferret is a more specific form of the action hunt)
(Other definitions for ferret that I've seen before include "European polecat bred for hunting rabbits" , "Rabbit-hunting polecat" , "Animal to hunt rats and rabbits" , "Polecat bred for hunting rats and rabbits" , "Search; type of polecat" .)
