The Critter Care Natural bedding for small animals suppresses ammonia odor caused by pet urine. Its soft pieces are designed to absorb up to three times its weight in liquids from pet urine or leaky water bottles, keeping your pet warm, cozy and dry. And, because it is virtually dust free, you'll experience less respiratory or allergy issues, as well as a cleaner habitat. All Critter Care Brand Bedding is made from reclaimed wood pulp and is biodegradable and compostable after use. Your pet will love to play and burrow and will have a warm nest for sleeping.
