Raised, as rabbits (4)
I believe the answer is:
bred
'raised as rabbits' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bred that I've seen before include "did produce issue" , "Very (music)" , "Procreated" , "Brought up (to behave in particular way)" , "Developed (animal variety)" .)
