This multi-functional scratching toy encourages your feline friends natural instinct, so make sure they find the missing piece! Available in two colors, the PUZZLE combines two products: a useful scratch pad to help your cat keep its claws in good condition and an intelligence toy which your cat can play with. The corrugated cardboard surface is surrounded by a track with two balls with bells which can be easily reached from the sides. The whirling motion of the balls will continue to stimulate your cat to come back for more. Every cat owner knows that their feline friends have a natural desire to hunt. Unlike outdoor cats, indoor cats have limited entertainment and exercise options during the day.
