JW's? Zippy Mouse Cat Toy gives your cat something to chase as it zips across the floor. No batteries required, pull the Zippy Mouse backward on a flat surface, then watch it zip away! The quick "zippy" movement replicates prey movement that will engage your cat's instinct to hunt and catch their prey. Great for interactive play between cats and their pet parents, the Zippy Mouse is lightweight and is covered in felt material that makes it easy for your cat to paw at or carry off to hide. Works best on flat, hard surfaces. Not for use on carpet.
