The customizable dual Treat Meters™ randomly dispense kibble and treats as the ball tumbles around. The Kibble Nibble also features rubber bumpers to minimize noise and marks on walls and floors. Each toy is appropriately sized to hold a dog's entire meal. Unscrews for easy loading and quick clean-up.
