Funny cat with hat and stick? (6)
I believe the answer is:
attach
'stick?' is the definition.
(sticking is a kind of attaching)
'funny cat with hat' is the wordplay.
'funny' indicates an anagram.
'with' says to put letters next to each other.
'cat' after 'hat' is 'hatcat'.
'hatcat' anagrammed gives 'ATTACH'.
'and' acts as a link.
(Other definitions for attach that I've seen before include "Append, join" , "Join or seize by law" , "Join onto" , "Append, affix" , "Annex" .)
