Kittens to play — getting most tangled (9)

I believe the answer is:

knottiest

'most tangled' is the definition.
('knotty' can be a synonym of 'tangled')

'kittens to play' is the wordplay.
'play' indicates anagramming the letters.
'kittens'+'to'='kittensto'
'kittensto' anagrammed gives 'KNOTTIEST'.

'getting' is the link.

(Another definition for knottiest that I've seen is " Most complicated".)

I've seen this clue in The Guardian.
