Catty Pope? (7)
I believe the answer is:
leonine
I believe this clue is a double definition.
'catty' is the first definition.
(thesaurus)
'pope?' is the second definition.
(I've seen this before)
(Other definitions for leonine that I've seen before include "verse" , "about a big beast" , "Like the king of the beasts" , "like one with largest share" , "None lie (anag) - like a lion" .)
