The Laser Cat Toy is an interactive toy. This tantalizing prey can't be caught. Make the harmless, quick-moving laser dot fly across the room, scale walls, or jump from one surface to another. Rest and relax while providing kitty with plenty of entertainment. The range on this small 2-1/2" toy is an incredible 1/2 mile! Several fun laser tips (designs may vary) and two LR44 button batteries included. Operating voltage 3V. Do not shine directly in eyes.
