In May 2015, Principal fully funded the Red Star Rescue Team of the American Humane Association for the rescue and rehabilitation of 150 dogs that had been injured and displaced by tornadoes and floods in Oklahoma and Texas. The following year, she created the Moki fund to help rescue animals and provide medical care so that they can be adopted into permanent homes. In August 2016, Principal worked with the American Red Cross to provide shelter and food for the victims of the 2016 Louisiana floods, as well as the American Humane Association to help rescue and shelter animals that were displaced in Louisiana and attempt to reunite them with their owners.
