KONG ® Bat-A-Bout toys provide mental stimulation and fulfill cats instinctual desires to chase, hunt and capture. The KONG Bat-A-Bout Chimes internal jingle is music to cats ears and primes curious kitties for an active play session. The unpredictable wobbling action invites hearty games of bat and swipe while the easy-to-refill KONG Premium North American Catnip belly-basin extends playtime.
