What it is: Adopt-a-Pet.com is North America's largest non-profit homeless pet adoption Web site. It began in 2000 as "1-800-Save-a-Pet.com," a program to help end the overpopulation of animal shelters in Los Angeles; today, over 12,000 animal shelters, rescue groups, SPCAs, and humane societies use its free service to advertise their adoptable animals.
How it works: Go to adoptapet.com, enter your zip code, and search its database for the perfect pet or for a shelter or rescue near you.
Why it’s unique: In addition to dogs and cats, Adopt-a-Pet.com lists rabbits, gerbils, ferrets, hamsters, farm animals, amphibians, and birds. Don’t see the animal you want? Check out the “Search Saver” feature, which sends you alerts when an animal that matches your criteria is entered into its system.
