The same is true for Daffy, Tweety, Sylvester, and so on. Really only Porky stands out as being a "person" rather than a pig.
But mickey mouse is never a mouse. He doesn't live in a wall and eat cheese; he has the shape of a mouse, but he drives around in a car and he often has a job and does people stuff. His nemesis happens to be a cat, but that doesn't appear to have anything to do with why they don't get along: Mickey and Pete are at odds with each other for PEOPLE reasons. Donald and Goofy are the same way.
So we're invited to imagine a world where instead of people, there are animals doing people things. Which works fine right up until you insert some humans, then the whole premise gets weird.
