Straw is normally used for a bedding material, while hay is used as a feed supplement. Straw is dried out and works well for building nests and providing cushioning for animals to sleep in. It is not moist like hay and is unlikely to mold.
Straw is derived from grasses and is regarded as a renewable building material since its primary energy input is solar and it can be grown and harvested. Straw bales were first used for building over a century ago. Straw is the springy tubular stalk of grasses like wheat and rice that are high in tensile strength. It is not hay, which is used for feeding livestock and includes the grain head. Straw is composed of cellulose, hemicellulose, lignins and silica.
