As a "cat person", I think there is another dimension that's somewhat related to introvert/extrovert, but not the same - independence vs hierarchy (aka boundaries). If a cat doesn't want you to interact with them in some way, they're going to react negatively regardless of their opinion of you. They're essentially their own independent entities who come together by mutual consent. That is an anathema to someone expecting to dictate the agenda for those "under" them, which I suspect is responsible for that tired refrain that cats don't love their owners.
