I believe the answer is:

marmalade

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

'cat?' is the definition.
(I've seen this before)

I don't understand the rest of the clue.

(Other definitions for marmalade that I've seen before include "confiture" , "Orange preserve" , "Breakfast preserve" , "Kind of cat" , "Orange jam" .)

I've seen this clue in the Evening Standard.
