Anthropomorphic sub-species...

I know this is old news, but let me get this straight. Mickey Mouse is a mouse who has a pet dog, Pluto, and a best friend, Goofy, who is also a... dog? Pluto walks on all fours and wears a collar, but no gloves. Goofy, a biped, wears shabby street clothes and white gloves, and though goofy, seems to possess a certain rational capacity. I can't tell if this is a form of divine madness or ruthless cartoon apartheid. Curious to see how Disney's anthropomorphic puzzle evolves in the coming makeover.
