Pets Evacuation and Transportation Standards Act
The Pets Evacuation and Transportation Standards Act (PETS) was a bi-partisan initiative in the United States House of Representatives to require states seeking Federal Emergency Management Agency (FEMA) assistance to accommodate pets and service animals in their plans for evacuating residents facing disasters. For pets that are not service animals, states must still follow the laws regarding service animals during a disaster.
