Feather Whirl Electronic Motion Toy
The Feather Whirl combines the excitement of a wand toy with the automatic and erratic motion of an electronic cat toy. The weighted base of the Feather Whirl creates a unique wobble motion while the real spinning feathers at the tip of the wand activate your cat's natural instinct to swat and pounce. The whisper-quiet motor turns on with a touch of a button. Feather Whirl is guaranteed to become one of your cat's favorite toys!
The Whistle Wand shakes up some fun with whistle sounds that drive cats batty with every shake! Available at Menards and other fine retailers.

Cassandra's Review- I think the type of cat you have and play level will change the effectiveness of fun that each toy offers. They might be amazing for one cat and blah to another. The feather whirl kind of caught an interest for a few minutes but none of the cats bothered to do more then sit and watch it. The wand presented a slight bit more fun but I think that the noise bothered my cat and me far more then created fun.
