Pets leave California with geese (7)
I believe the answer is:
noodles
'geese' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for noodles that I've seen before include "idiots!" , "Far Eastern food" , "Oriental pasta" , "Fools; pasta" , "Egg pasta; simpletons" .)
