Believe this. My cats have been offered at least 20 other types of toys during their 10 years. From cheap or free to stupid expensive. No toys kept their attention for more than a day, except for those plastic springs. They make keep you up at night chasing the things. A down side is that they will lose them, so you'll have to keep replenishing the supply every 6months or so. And there will be scads of the things under the refrigerator and bathtub.
