Rabbit food? (3)
I believe the answer is:
bun
I believe this is a double definition.
'rabbit' is the first definition.
'food?' is the second definition.
(bun is a kind of food)
(Other definitions for bun that I've seen before include "Small rounded bread or cake" , "Sweet roll and hairstyle" , "Small cake; hair style" , "Tied hair" , "One from Chelsea" .)
