The Catit Design Senses Play Circuit is a toy which your cat will love. This fun game was created to stimulate all of your cat's senses. Cats have a highly developed sensory system and see and hear things that we cannot even start to imagine. They see and hear things which we cannot and they experience the world in a very different way to us. These well-developed senses are very important when hunting and the Catit Design Senses range provides your cat with activity centres and toys which allow it to indulge its extraordinary sense of sound, taste, feel and smell as well as satisfying its natural instincts. Peep hole design: There are peep holes in the track so that your cat can see, nudge and chase the ball. Grey-green ball: The ball is constructed to attract your cat's attention. Please note: this ball does not light up. Illuminating balls can be purchased separately. Circuit can be extended: Additional elements can be used to extend the track.
