I rather like Gryphons, most people think it's weird to be a half eagle/lion hybrid. I see no problem with it. Like many mythical beings, many are able to mate with those outside of their own races, either because their races is in danger of dying out, or because they have a natural affection for each other. I believe mythical creatures are neither mythical, or long gone. They exist somewhere in the world, but due to...human advances, they are frightened and no longer want to show themselves. Or, maybe a small peecentage of the worlds furries/scalies are actually those beings that have disguised themselves as humans to fit in more, but still retaining some of their animalistic traits.
