Whoa! I didn't think his ears worked. Until of course I saw that one with Animan. Then Chat Noir's ears go up and down when he realizes that, Animan is coming.
I think his ears are useful. Cat Noir used them in Animan and the ears went fop fop then he realizes that he can hear animan and he ducked down with Ladybug.
Also, i think his ears work.
What do you think?
