Kong Wubba Cat Friends BunnyKONG Cat Wubba Bunny is specifically developed to appeal to a cat's instinctive desire to stalk and capture prey. All Cat Wubba toys have a rattle sound and are infused with KONG's premium North American catnip for added attraction. The unique tails make a “crackle” sound that rewards contact and encourages continued play. Cat Wubba toys stimulate senses of sight, sound, smell and touch. The ultra-soft fabric and shape of the Wubba Cat Friends make it fun for your cat to snag, wrestle and snuggle.
