Prominent rabbit features (4)
I believe the answer is:
ears
'prominent rabbit features' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ears that I've seen before include "Lugs (colloq.)" , "Shakespeare 'Friends, Romans, countrymen, lend me your . . . .'" , "Walls are said to have them" , "Auditors" , "Organs for 7 down" .)
