I’m gonna make a short list here. Please don’t just randomly ship packages of supplies to Texas. It is better for the organizations to receive monetary donations they can use to buy what they need than to have a can of dog food arrive one day, a pack of blankets the next, and some pet Halloween costumes the day after that.
Houston is not the only city affected by the flooding and displacement.
Here we go:
Houston SPCA, as seen on “Animal Cops”. They’ll be doing a lot of physical rescue: http://www.houstonspca.org/give/
Gulf Coast Humane Society in Corpus Christi:
Houston Humane Society: http://www.houstonhumane.org/and their special Amazon wishlist:
SPCA of Texas: https://www.spca.org/
Humane Society of the United States (no, they’re nothing like PETA). They’ll be providing long term assistance to the shelters that have suffered from the flooding, and they’re providing disaster relief now: http://www.humanesociety.org
