Hurricane's impact on animals

As of late last week, rescuers had pulled more than 1,000 stranded animals from deserted parts of New Orleans. Wayne Pacelle, president of the Humane Society, said it is just a start. The need for animal rescue is much more expansive. Pacelle estimates about 60 percent of U.S. households have pets and more than 50,000 animals were probably stranded by Katrina.
