Capers (6)
I believe the answer is:
antics
'capers' is the definition.
('antic' can be a synonym of 'caper')
This is the entire clue.
(Other definitions for antics that I've seen before include "Cat's in (anag.)" , "comical capers" , "Buffoonery" , "Clowning" , "Funny movements and foolish behaviour" .)
