Do not take these puffy cat ears as merely ornaments or toys… as you may find they keep moving if the feeling of the person wearing them changes.
They’re controlled by brainwaves or other biosensors! Thus these ears may then tell us what your feeling is: they will stand up if you concentrate (e.g. encountering with a sexy girl in street) and they’ll drop down if you’re relaxed and comfortable. Sounds interesting? Try them to get real fun.
