They do not, but it's pretty clear that the ears and tail are fake by their material. Cat Noir's tail is a belt, and his ears have buttons holding them in.

Someone who worked on the show explained on Tumblr in an ask that "Cat noir’s tail-belt thing is most strange. There are times when it behaves like an inanimate object on its own but at times it also behaves like an actual cat tail to add humor or more flavor to the scene if needed. Is just an animation thing. (is the same gimmick like how a character’s hair would rise when they are angry or scared in a studio ghibli film)."
