Animal Health During Disasters and Emergencies in the US

When Hurricane Katrina struck the Gulf Coast in 2005, an estimated 250,000 animals were left behind — largely because evacuation orders made no provisions for pets, and owners faced the impossible choice between their own safety and their animals'. That single event reshaped federal disaster policy and accelerated the passage of the Pets Evacuation and Transportation Standards (PETS) Act in 2006. This page covers how animal health is protected — and frequently compromised — during disasters and emergencies across the US, from the legal frameworks that govern response to the specific scenarios where animal welfare becomes most fragile.

Definition and scope

Animal health during disasters refers to the coordinated systems, policies, and interventions that protect the physical and psychological wellbeing of animals before, during, and after a natural or human-caused emergency. The scope is broader than most people assume. It encompasses companion animals, livestock and farm animals, wildlife, aquatic species, and animals in institutional settings like shelters, research facilities, and zoos.

The PETS Act of 2006 amended the Stafford Act to require states and localities to address household pets and service animals in their emergency plans as a condition of receiving FEMA preparedness funding. The law was a direct legislative response to Katrina's documented failures. Before 2006, no federal mechanism required local governments to treat animals as anything more than property in evacuation scenarios.

The USDA Animal and Plant Health Inspection Service (USDA-APHIS) maintains primary federal authority over foreign animal disease incursions — a distinct but overlapping category of animal health emergency that includes events like foot-and-mouth disease outbreaks or highly pathogenic avian influenza.

How it works

Disaster response for animals in the US operates through a layered architecture. At the federal level, the National Response Framework designates Emergency Support Function #11 (ESF-11) as the coordinating mechanism for agriculture and natural resources, which includes animal health. USDA leads ESF-11 in coordination with the Department of the Interior and other agencies.

At the state level, most states have developed State Animal Response Teams (SARTs), which coordinate across government, veterinary associations, humane societies, and volunteer networks. As of the National Alliance of State Animal and Agricultural Emergency Programs (NASAAEP), 48 states have some form of organized animal emergency response framework, though the depth and funding of those frameworks varies significantly.

The mechanics of response during an active disaster generally follow this sequence:

Pre-event registration: Some jurisdictions maintain registries of households with animals requiring special evacuation assistance.
Co-located or separate sheltering: The PETS Act requires states to permit people to evacuate with pets; emergency shelters may be co-located (humans and animals in adjacent spaces) or separate, species-specific facilities.
Field rescue and triage: Responders trained in large-animal rescue use specialized equipment — lift bags, water rescue sleds, trailer configurations — that differs sharply from small-animal response.
Veterinary emergency care: Mobile veterinary units, often coordinated through state veterinary medical associations, deploy to provide emergency care and triage in affected areas.
Disease surveillance post-event: Crowded shelter conditions create rapid disease transmission risk; respiratory illness and gastrointestinal pathogens spread quickly among stressed, immunocompromised animals.

Animal mental health and behavior is an underrecognized dimension of disaster response. Chronic stress from displacement, separation, and environmental disruption produces measurable behavioral changes in dogs and cats that can persist for months post-event, complicating adoption and reunification outcomes.

Common scenarios

The disaster scenarios most likely to affect animal health in the US fall into distinct categories with different operational demands:

Hurricanes and flooding drive the highest volume of animal displacement events. Storm surge and inland flooding leave animals stranded on rooftops or in submerged structures. Large animals, including horses, cattle, and goats, cannot be rapidly evacuated without specialized trailer resources that are often in short supply.

Wildfires present a different challenge: speed. The 2018 Camp Fire in Paradise, California destroyed over 18,000 structures in under 24 hours (Cal Fire Incident Report), leaving minimal time for organized animal evacuation. Burns, smoke inhalation, and hoof damage from hot ground are the primary veterinary injuries in wildfire events.

Disease-based emergencies — particularly foreign animal disease outbreaks — activate a separate federal-state response architecture. A confirmed foot-and-mouth disease detection would trigger livestock movement bans, quarantine zones, and potential mass depopulation under USDA-APHIS authority. The economic and welfare scale of such an event would be enormous.

Winter storms and extreme cold cause hypothermia, frostbite, and structural collapse of livestock housing. The 2021 Texas freeze killed an estimated 1.3 million cattle, poultry, and swine across the state (Texas A&M AgriLife Extension, 2021).

Decision boundaries

Not every emergency activates the same response tier, and understanding where boundaries fall matters for how animal health resources are deployed.

The critical distinction is between a declared federal disaster under the Stafford Act — which unlocks FEMA funding and activates ESF-11 — and a state or local emergency declaration, which relies entirely on state resources and mutual aid agreements. Animals in non-declared events receive no federal assistance, regardless of severity.

A second boundary involves livestock versus companion animals. Livestock health emergencies route through USDA and state departments of agriculture. Companion animal emergencies route through emergency management and humane organizations. The two systems have historically operated in silos, which is why one-health frameworks that integrate human, animal, and environmental health across agencies have gained traction as a structural improvement.

The animal health regulations governing the US create the baseline legal obligations, but enforcement during an active disaster is rarely the operative concern — capacity and coordination are. The broadest resource for navigating animal health across stable and emergency conditions is the animal health information hub that aggregates guidance across species, scenarios, and care contexts.
