Petfinder is an on-line, searchable database of animals that need homes. It is also a directory of over 9,000 animal shelters and adoption organizations across the USA, Canada and Mexico. Organizations maintain their own home pages and available pet database.

Their mission: to use Internet technology and the resources it can generate to 1) increase public awareness of the availability of high-quality adoptable pets and to 2) increase the overall effectiveness of pet adoption programs across North America to the extent that the euthanasia of adoptable pets is eliminated.

From the comfort of their personal computers, pet lovers can search for a pet that best matches their needs. They can then reference a shelter's Web page and discover what services it offer. Petfinder also includes classified ads, discussion forums and a library of animal welfare articles. Petfinder is updated DAILY.

Petfinder is made up of animal-care professionals and regular people volunteering for their local animal welfare organizations all working together to maintain active and accurate homeless pet lists. Most animal welfare volunteers have "real jobs" by day. The success and the magnitude of this project is largely due to their tireless efforts to make a difference.
