Need your cat to exercise more or slow them down when they eat? Our cat treat feeder balls can do both and more! Fill the ball with treats, or their favorite dry food, and place the ball on the floor and watch them go. Our balls are also designed to work in a variety of ball chase tracks that you might already own, or if you are a retailer it's a great add to a track. This pack also comes with an interchangeable top with a butterfly shape opening to accommodate smaller treats or to make it a bit harder to get the treats out of the ball. Our balls are made from a plant-based, FDA food safe material which contains no toxic dyes. Plus, they are recyclable AND industrial compostable. Available in 8 vibrant colors. Some even sparkle!
