Cattle complaint (4)
I believe the answer is:
beef
I believe this clue is a double definition.
'cattle' is the first definition.
(beef is a kind of cattle)
'complaint' is the second definition.
(beef can mean a complaint or objection)
(Other definitions for beef that I've seen before include "it's unacceptable for vegetarian" , "Muscle; meat; grievance" , "Grumble over cattle meat?" , "Strength - grievance" , "Meat - complaint" .)
