KONG Kitten Chirpz Chick's motion-activated sound chip calls your kitty to play with an irresistible song, which triggers Kitty's natural curiosity and instincts to chase and pounce. This chick, designed for smaller kitty paws, is made for batting with flexible paws and tail feathers that flap when thrown for added excitement, while the North American Premium Catnip Knip adds to the fun.
