I was put out about noisy strays (5)
I believe the answer is:
waifs
'strays' is the definition.
(I've seen this in another clue)
'i was put out about noisy' is the wordplay.
'put out' means one lot of letters goes inside another.
'about' is an insertion indicator.
'noisy' becomes 'f' ().
'i' placed inside 'was' is 'wais'.
'wais' going around 'f' is 'WAIFS'.
(Other definitions for waifs that I've seen before include "Forsaken children" , "Strays" .)
