Cats are curious animals and love to bat at things. A number of toys have been produced to entertain cats such as soft balls attached to a string which is connected to a rod that can be held by the owner or mounted to say a window sill. However if the owner has to hold the rod and cause the ball to dance, they soon become bored with the game or have other things they need to do. If the rod is mounted and the ball is static, the cat quickly becomes bored and does not play with the toy. A number of solutions have been proposed to solve this problem where the ball or toy is moved by some sort of motor. Unfortunately, these are expensive to produce, take up a lot of room both in shipping and in the customer's home, and are prone to breaking.
Thus there exists a need for a simple, inexpensive, space efficient cat toy that keeps cats and other pets engaged.
