Kitty container (3)
I believe the answer is:
pot
This clue is a double definition.
'kitty' is the first definition.
(I've seen this before)
'container' is the second definition.
(pot is a kind of container)
(Other definitions for pot that I've seen before include "Cooking vessel or slang marijuana" , "Saucepan" , "Container for 23" , "Sink (a snooker ball)" , "Shoot; pan" .)
