anyone got petpoint adoptable animals showing on a squarespace site?

Check it on a phone once it's in. Iframes with a fixed height often end up as a little scrolling box inside the page on mobile, which is horrible to use. Give it a generous height, or put it on its own page with nothing else on it.

PetPoint can produce an adoptable-animals search page meant for embedding, so ask whoever admins the PetPoint account to find the website/adoptable search settings and get the embed URL. On Squarespace, put an iframe pointing to it inside a code block. Code blocks with embeds need one of the plans that allow custom code, so check the rescue's plan first. Alternative route: lots of rescues have PetPoint push to Petfinder automatically and then use Petfinder's widget on the site. Either way it updates itself and nobody copies anything over.
