Do a feline out of a male (5)
I believe the answer is:
cheat
'do' is the definition.
(do can mean to cheat or defraud)
'a feline out of a male' is the wordplay.
'a feline' becomes 'cat' (cat is a kind of feline).
'out of' means one lot of letters goes inside another (some letters on the outside of others).
'a male' becomes 'he' (he refers to a man).
'cat' going around 'he' is 'CHEAT'.
(Other definitions for cheat that I've seen before include "Teach? (Anag)" , "Swindler - crib" , "22 [FRAUDSTER]" , "Con" , "Welsh" .)
