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 kitty’s 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. Details: Absolutely NO assembly required! Like having a purrsonal trainer for your cat. Purrfect for every type of cat: kitten, young at heart, full-figured, senior, or just plain lazybones! Takes 3 AA batteries (regular or rechargeable). Dimensions: 29.5” long x 5” wide x 2.5” deep.
