Cribbed from Mark's blog:

The website of the Humane Society. Help animals displaced by the hurricanes, and send your Congressperson a letter (on the website so all you gotta do is click it through) asking them to support the PETS Act, which would help keep people together with their pets during evacuations. Many of the people who did not evacuate stayed because they didn't want to leave their pets behind. As a pet owner, I understand this feeling. They aren't just dogs or cats or whatever, they're family. I've had Thumper for 15 years. Miss Kitty was with me for 18 years of her 19 1/2. I couldn't leave them behind. No one should have to make that choice.
