Moisture Absorption:

Like thousands of tiny sponges, the 100% pure, kiln-dried pine in our pellet bedding absorbs all moisture, naturally neutralizing the ammonia in liquid waste. And because it absorbs so quickly, moisture does not spread under the bedding. You only have to clean out small areas, reducing the amount of product used. Look how Equine Pine pellet bedding compares to a major national shavings brand in recent 3rd party testing.
