KONG Cat Wubba 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 Hugga Wubba cat toy is covered in an ultra-soft fleece with an irrestible texture that makes it fun for cats to claw, tackle and wrestle.
