With more than 100 participants representing various Animal Control Agencies, Humane Societies, the ASPCA, and non-profit organizations from over 15 jurisdictions, we developed and executed a pet shelter drill for a major metropolitan region. The field drill tested the region's capabilities to set-up, operate, and take-down emergency pet shelter facilities following an emergency event. It also served as an invaluable opportunity for various animal care organizations within the region to coordinate with each other.
