Feline has uncovered some entertainment (7)
I believe the answer is:
cabaret
'some entertainment' is the definition.
(cabaret is a kind of entertainment)
'feline has uncovered' is the wordplay.
'feline' becomes 'cat' (cat is a kind of feline).
'has' indicates putting letters inside.
'uncovered' becomes 'bare' (similar in meaning).
'cat' enclosing 'bare' is 'CABARET'.
(Other definitions for cabaret that I've seen before include "Bob Fosse musical with Liza Minnelli" , "Revue" , "Floor show for Arab etc" , "Entertainment at night club" , "Bear cat (anag.)" .)
