Instincts by SmartyKat Zingy Zebra releases your cats inner instincts by gliding like a bird through the air when tossed, enticing your cat to stalk, leap, and chase. Containing HappyNip Silvervine and Catnip blend, feathers, and felt, this toy will satisfy your cats need to hunt with safer and kinder prey. For best gliding motion, spread and fluff out the feathers and felt. Like a birdie, this toy moves in a downward trajectory, toss at an upward angle for a longer glide.
