Endless barbecue arranged for young carnivore (4,3)
I believe the answer is:
bear cub
'for young carnivore' is the definition.
(bear cub is a kind of young carnivore)
'endless barbecue arranged' is the wordplay.
'endless' means to remove the last letter.
'arranged' indicates anagramming the letters (letters rearranged).
'barbecue' with its final letter removed is 'barbecu'.
'barbecu' is an anagram of 'BEAR CUB'.
(Other definitions for bear cub that I've seen before include "Ursine baby" , "Paddington, perhaps" , "Young carnivore" , "youngster?" .)
