No cat can live on sleep and food alone. They need a little Fling-Ama-String too! This battery-operated, action-packed, string-flinging machine hangs on any standard door knob. One end of a long, brightly-colored, silky cord is sewn onto a flat, elastic conveyer belt which is constantly rotating. The cord flings in and out for kittys non-stop amusement. Cats can bite, paw, claw, and ultimately stop the string. As soon as they let go, the string automatically starts to rotate again and again and again! The toy has 2 speeds for the frisky or faint feline. Just turn it on, take a seat, and watch kitty go.
