BREAKING DOWN 'Unintentional Tort'. In certain cases, a person causing an accident may be held legally responsible for their negligence and may have to pay a plaintiff for physical injuries, property damage and/or financial loss.
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 almost has an almost exclusively yellow color when it is baled, and just a hint of smell. Hay bales can look like a greenish coarse grass, fine grass, or even flowery and weedy grass; it entirely depends on what plants were cut and dried to make the bales.
