The Shelter Pet Project's website allows visitors to find local animal shelters by simply entering a ZIP code. Also, city or county health and police department phone book listings often contain local animal shelters' contact information.
Searching "animal shelter," "humane society" or "animal control" online often yields results for local animal shelters. In addition, organizations such as the Shelter Pet Project, Petfinder and AdoptAPet.com also provide information regarding adopting pets, low-cost spay and neuter options, as well as volunteer opportunities. Other useful resources, such as those explaining the differences between different kinds of animals and their respective breeds, can also be found.
