Performs an adaptation of Cats (4)
I believe the answer is:
acts
'performs' is the definition.
(acting is a kind of performing)
'adaptation of cats' is the wordplay.
'adaptation of' is an anagram indicator.
'cats' anagrammed gives 'ACTS'.
'an' is the link.
(Other definitions for acts that I've seen before include "Behaves like thespian" , "New Testament book immediately following the Gospels" , "Major divisions of play" , "performers for revue, say?" , "placed before Romans?" .)
