Where puss may be in a tight spot? (6)

I believe the answer is:

corner

I'm a little stuck... Click here to teach me more about this clue!

'spot?' is the definition.
(I know that corner is a type of carrefour)

I don't understand the remainder of the clue.

(Other definitions for corner that I've seen before include "pickle" , "Establish exclusive control" , "Awkward position" , "Where rook starts on the chess board" , "Where rook is immobilised, initially" .)

I've seen this clue in the Evening Standard.
