Pangaea?

(pan-gee-ah)

If you don't remember the meaning of Pangaea, the word probably seems slightly familiar. Pangaea (Greek for, "all lands") is the name Alfred Wegener used to refer to the super-continent that existed during the Mesozoic era, before the process of plate tectonics separated the component continents. We think a planet Where Pets Rule the World and are cherished on "all lands" would be a pretty good place to live. Our logo represents that place for us. We hope to be the "supercontinent" that can help the pets and their humans in this community find all the goods they need. Okay, okay, we know . . . the logo isn't exactly just one continent. But, for artistic reasons, it was as close as we could get.
