It drives rabbits from their holes (6)
I believe the answer is:
ferret
'it drives rabbits from their holes' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for ferret that I've seen before include "Kind of weasel, a rabbit hunter" , "Small fierce animal used to hunt rabbits" , "Rabbit-hunting polecat" , "Small fierce animal, rabit hunter" , "Small animal used to drive rabbits from burrows" .)
