Sound of cat rouses birds (10)

I believe the answer is:

kittiwakes

'birds' is the definition.
(kittiwake is a kind of bird)

'sound of cat rouses' is the wordplay.
'sound of' indicates a 'sounds like' (homophone) clue.
'cat' becomes 'kitty' (informal term for a cat).
'rouses' becomes 'wakes' (I've seen this in another clue).
'kitty' is a homophone of 'kitti'.
'kitti'+'wakes'='KITTIWAKES'

(Another definition for kittiwakes that I've seen is " Birds".)

I've seen this clue in The Times.
