Sometimes, he's not thinking about you. Live with it. Don't ask him what he's thinking about unless you are prepared to discuss such topics as navel lint, the shotgun foundation and monster trucks. Get rid of your cat. And no, it's not different, it's just like every other cat.
Dogs are better than ANY cats.
It's like the full moon or the changing of the tides. Let it be. Shopping is not a sport. Anything you wear is fine. You have enough clothes.
