This is the brain wave reading headband with furry ears that move in response to your thoughts and moods like an actual feline’s. A research-grade forehead EEG sensor translates the electrical impulses given off by your brain into a corresponding motion in the motorized ears. When you are paying attention, the ears quickly perk up. When you are in a relaxed state, the ears slowly droop down. When something particularly piques your interest—perhaps the sight of a similarly outfitted person—the ears stand at attention and wiggle back and forth. The lightweight plastic headband fits most head sizes. Requires four AA batteries. 7 3/4" H x 4 1/2" W x 10" L. (8 oz.)
