Bear the edges of paranoia? (5)
I believe the answer is:
panda
'bear' is the definition.
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for panda that I've seen before include "Raccoon-like animal" , "shoots lover" , "Large bear from the bamboo forests of China and Tibet" , "giant animal" , "Black and white Chinese bear" .)
