The floor just became a lot more fun thanks to this cat toy! This mobile laser toy moves around the floor while its laser tail follows behind and creates patterns that are visually interesting to your pet. The toy always moves away from the laser so your kitty is the one creating the chase, not the other way around. The toy automatically turns off after 10 minutes to keep your cat from being over-stimulated by the moving toy. Press the single button on the underside of the Laser Tail, set the toy down and let playtime begin. The toy uses three alkaline AA batteries (not included).
