PetPress brings PetPoint, PetFinder and Animals First integration to your website, allowing you to create lists and detail pages for your adoptable animals. Lists are sortable, and detail pages each have their own URL for easy social sharing. Easy to implement for the do-it-yourselfer, but fully configurable for the professional web designer. By using a shortcode, you can list animals in a shelter location by species, or you can show the details of an individual animal.

PetPress

PetPress allows PetPoint, PetFinder and Animals First users to create lists and detail pages for animals in their shelter(s).
