Catty comment (4)
I believe the answer is:
meow
'catty comment' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for meow that I've seen before include "Catty remark" , "Tom's plea for attention" , "Beastly noise" , "Crying sound of an animal" , "reply to spiteful dig" .)
