About The Animal Rescue Site
The Animal Rescue Site focuses the power of the Internet on a specific need — providing food for some of the 27 million unwanted animals given to shelters in the U.S. Every year. Over 10 million animals are put to death every year in the U.S. Alone because they are abandoned and unwanted.
Each click on the purple "Click Here to Give - it's FREE" button at The Animal Rescue Site provides food and care for a rescued animal living in a shelter or sanctuary. Funding for food and care is paid by site sponsors and distributed to animals in need at the Fund for Animals' renowned animal sanctuaries (including Cleveland Amory Black Beauty Ranch in Texas and the Wildlife Rehabilitation Center in California), pet shelters supported by the Petfinder Foundation, North Shore Animal League, and other worthy animal care facilities supported by the GreaterGood.org foundation.
100% of sponsor advertising fees goes to our charitable partners.
