The Catit Senses 2.0 Ball Dome is an automated ball cat toy that helps keep your cat entertained when you're not at home. The inner swiveling plate sends the ball rolling for your cat to paw at. The Ball Dome has two play modes. While in Sensor mode, the toy is activated by motion sensor anytime your cat is nearby. While in Continuous mode, the toy is powered on until it is switched off. The ball can be opened to insert toys or catnip for extra enticement.
