Cats are loving, loveable, and supremely confusing. Creative cat owners have created plenty of webcomics to try to come to terms with their bewildering behavior and how infuriating (and wonderful) it can be to live with them.
Much of their bizarre behavior (or, as we like to call it, 'cat logic') stems simply from a misunderstanding between species. Cats are not nearly as social as us, so many of their behaviors that we understand to be social or asocial are done for entirely different reasons. Rubbing up against someone, for example, is more of a way for them to mark you as their territory than a show of affection!
