The Mystery Motion replicates the darting and dashing of a real mouse and the battery-operated control base in the center lets you set the speed of the mouse’s movement. Save to Shortlist Your cat’s brain is hardwired to respond to erratic movements – just like those delivered by Mystery Motion. This cat toy replicates the darting and dashing of a real mouse to get your cat up off the sofa and playing. The erratic movement of Mystery Motion’s concealed mouse keeps your cat guessing (like when you place your hand under a blanket and move it around to make your cat pounce). A battery operated control base in center lets you set the speed of the mouse’s movement.
