Kong Cat Natural products are designed to appeal to a cat's natural instinct to hunt and KONG Cat Cork Ball encourages and refines your cat's natural instincts to hunt and capture prey.

The cork ball is soft and can be easily squeezed by both owner and cat, while the animal-like design of the toy will keep your cat playing. It is made from ultra-light materials, so your cat can easily tumble around with it.
