Main Resources for Finding Pets
Petfinder.com: ALL found/rescued Katrina & Rita pets are supposed to be listed on this website (with photograph & detailed information). Obviously, a lot of this info got lost along the way, but this is a good place to start when searching for pets. Make sure to try different search techniques since a lot of breeds are identified incorrectly. Also, the sex of many pets is not listed.
PetHarbor.com: Similar to Petfinder but usually more information on the current or previous location of pets.
Lost and Found Pet Search: New database that accesses information from SEVERAL other databases for Katrina/Rita lost & found pets. If above link does not work, try this one.
ASPCA List: List of "all known" US shelters fostering rescued pets.
FindKatrinaPets.com: List of online sites (with photos) for finding Katrina & Rita pets. Also listed: Louisiana shelters, Mississippi shelters, and shelters in other states.
