Tens of thousands of household pets were separated from their owners in the aftermath of Hurricane Katrina. In this special episode of Nature, we travel with animal rescue teams by small boat through the flooded streets of the devastated city, searching for stranded animal survivors. We're there as they retrieve the animals, and then, amazingly, amidst all the chaos and destruction, reunite the lucky few with their owners. Along the way, we'll see what happened to the other animal inhabitants of New Orleans -- from the zoo and aquarium to the wildlife of Lake Pontchartrain.
