Using the KONG Cat Gyro is super easy. First, remove the middle container and fill it with your cat's favorite food or treats, up to 1/3 cup. Then put the container back in the toy. Place the toy on the floor and let your cat discover it. Your cat will bat at it, and the roll and flip action will start dispensing the treats. As for maintenance, it's important to clean the middle container regularly. You can easily take it out and wash it with mild soap and water. Make sure it's completely dry before refilling. Also, keep an eye on the toy for any signs of wear and tear. If the bell or the catnip scent starts to fade, it might be time to replace the toy to keep your cat engaged.
