SmartyKat Wobble Wings Electronic Sound Wobble Cat Toy helps to satisfy your cat's natural desire to hunt with a kinder "prey." The soft touch bird cage rolls & wobbles attracting cats to pounce & chase; while dangling feathered plush bird sings with motion-activated bird sounds. With a bat of the paw, your cat is on the hunt! Toys that mimic the thrill of the hunt, encourage even inactive cats to chase, pounce and leap.
