Gratify black and white animal, say (6)
I believe the answer is:
pander
'gratify' is the definition.
(thesaurus)
'black and white animal say' is the wordplay.
'black and white animal' becomes 'panda' (I've seen this before).
'say' shows a homophone (sound like).
'panda' sounds like 'PANDER'.
(Other definitions for pander that I've seen before include "Indulge or cater to" , "Gratify weakness like a pimp" , "Bow (to)" , "Cater for debased taste" , "Indulge, gratify desires" .)
