Just as law enforcement personnel and the military did search and rescue for people following Katrina, so did animal rescue groups from all over the United States. I can tell this was not a local group because the "river" is Bayou St. John and the "beavers" are nutria. There are still groups who make daily rounds to feed and water animals whose owners have never returned. Thousands of animals have been shipped to shelters in all parts of the country and owners can search on the web for them.
I carry sacks of cracked corn in my car for the ducks, geese and waterfowl at Lafreniere Park and City Park and bags of cat and dog food for the abandoned animals in the metro area. They are all God's creatures, great and small and their eyes say so much when they see me.
