You can often tell your cat’s emotions by the position of its ears. Now through the wonders of brain wave technology and a whimsical design that mimics cat ears, you can buy wearable cat ears that let other people know your emotions.

The ears will perk up when you’re paying attention to something, lie dormant to each side when you’re relaxed, and wag back and forth when you’re enthusiastic about something. By wearing these cat ears, you can let the world around you know your emotions without uttering a word, just like a real cat.
