Celestial feline (3)
I believe the answer is:
leo
'celestial feline' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for leo that I've seen before include "of pride" , "Man" , "Cancer, ___, Virgo" , "Singer-songwriter Sayer, b. 1949" , "Astrological sign" .)
