Kitty gets sailor shot (7)
I believe the answer is:
jackpot
'kitty' is the definition.
(I know that kitty can be written as jackpot)
'sailor shot' is the wordplay.
'sailor' becomes 'jack' (informal term for a sailor).
'shot' becomes 'pot' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'jack'+'pot'='JACKPOT'
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for jackpot that I've seen before include "Cumulative prize" , "Accumulated prize" , "Big win from one-arm bandit" , "pool" , "best prize!" .)
