The finely chopped straw component creates a superior litter that is highly absorbent to control ammonia and other odours. At The Straw Boss we are a leader in caring for our environment, as straw is 100% renewable, biodegradable and compostable. No chemicals have been added to ensure it is safe for you and your pets.
