Kitty is a dish (3)
I believe the answer is:
pot
I believe this is a double definition.
'kitty' is the first definition.
(synonyms)
'dish' is the second definition.
'is a' acts as a link.
(Other definitions for pot that I've seen before include "Cannabis; sink (snooker)" , "...Karenina(Tolstoy)" , "Ceramic vessel" , "Cooking utensil or illegal drug" , "Cylindrical container" .)
