KONG is proud to introduce "The Ultimate Cat Toy," Hugga Wubba. The original Cat Wubba was inspired by KONG's popular Wubba dog toy and is the perfect size for batting around. Wubba for cats stimulates senses of sight, sound, smell and touch. All Hugga Wubba toys contain pure North American catnip rattle and have tails that make a crinkle sound.
