Pool of money for cat? (5)
I believe the answer is:
kitty
I believe this clue is a double definition.
'pool of money' is the first definition.
(I've seen this before)
'cat?' is the second definition.
(kitty is a kind of cat)
'for' acts as a link.
(Other definitions for kitty that I've seen before include "Pot of money" , "Little cat" , "Jack" , "Pool - puss" , "Perhaps a small Abyssinian" .)
