Using this Kaytee bedding is easy. Just spread it evenly at the bottom of your pet's cage. Make sure to fill it to a depth that allows your pet to burrow and nest comfortably. As for the amount, it depends on your cage size, but 500 cu. in. should cover a small - to medium - sized cage well. When it comes to cleaning, check the bedding daily. Remove any soiled parts right away. If it starts to smell, it's time for a full change. To keep it fresh for longer, place your pet's food and water away from the bedding area. Store any unused bedding in a cool, dry place to maintain its quality.
