The thing with this is animals that can be pets are realistically going to be at the top and maybe tasty ones. I mean if you talking if only two animals only existed on the planet or something. But if you take that out. mmmm I mean I think about the air and the ocean and all the experience they hold. Bats are so beneficial but that feels a bit like the pet and food thing. Utilitarian. If its cool factor. Maybe dolphin and osprey.
