Whistle for feline, and shout (7)
I believe the answer is:
catcall
'whistle' is the definition.
(type of whistling noise)
'feline and shout' is the wordplay.
'feline' becomes 'cat' (cat is a kind of feline).
'and' is a charade indicator (letters next to each other).
'shout' becomes 'call' (synonyms).
'cat'+'call'='CATCALL'
'for' acts as a link.
(Other definitions for catcall that I've seen before include "disapproving expression" , "taunt from the audience" , "Feline whistle of disapproval" , "Derisive cry" , "Mocking remark" .)
