Why do families refuse to evacuate?
Pets are one of the reasons, and FEMA says so plainly. In past disasters, pet owners have chosen not to comply with evacuation orders when accommodations for their animals couldn't be guaranteed, which raised the risk for evacuees, responders, and animals alike.
Hurricane Katrina made the scale of it visible. Congressional debate at the time cited up to 600,000 animals that died or were left without shelter.
What the PETS Act did, and didn't do
Congress responded in 2006 with the Pets Evacuation and Transportation Standards Act. It requires state and local emergency plans to account for household pets and service animals in order to qualify for FEMA funding.
What it doesn't do is require any particular shelter to take your pet. Hotels aren't required to either, though that rumor circulates every hurricane season.
So more communities have a pet-friendly shelter than before 2006. Finding yours is still your job, and worth doing before a storm is named.
What pet-friendly shelters require
This is where most families get caught. Shelters that accept animals typically ask for proof of licensing and vaccination, and often expect you to bring a crate and food.
Gathering records while tracking a storm is how people run out of time.
What the bundle handles
The supplies are packed. Food, water, bowls, and a leash are already together.
You add the records and the carrier. Then the only open question is which pet-friendly hotel along your route still has a room.
