Rabbit-like animal (4)
I believe the answer is:
hare
'rabbit-like animal' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for hare that I've seen before include "may be electric!" , "Timid creature" , "As mad as this March animal" , "'You can't run with the . . . . and hunt with the hounds'" , "Swift rodent" .)
