Girl entertained by hares and rabbits (6)
I believe the answer is:
sandra
'girl' is the definition.
'entertained by hares and rabbits' is the wordplay.
'entertained by' says the answer is hidden in the clue (the clue hosts or entertains the answer).
'SANDRA' can be found hidden inside 'hares and rabbits'.
(Other definitions for sandra that I've seen before include "girl" , "woman's name" , "Girl's name" , "So woman" .)
