Add zip code search?

The petfinder plugin is targeted towards shelters so my development is concentrated on listing pets available with a shelter and not replicating features like searching for pets in an area which Petfinder does a great job of on its own. The Petfinder website would be a lot faster for users than going through an API also.

My client would like to keep visitors on their site because of other relevant information. Also, they don’t want every shelter in a particular zip code included in the result set; so I need to limit by shelter ID, too. That is the use case for wanting search and results added. Thanks for the reply.
