The floor just became a lot more fun thanks to the PetSafe Laser Tail Automatic Laser Light Cat Toy! This mobile laser toy moves around the floor while its laser ÒtailÓ 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 Laser Tail 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 Laser Tail uses 3 alkaline AA batteries (sold separately).
