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 formation and monster trucks. Get rid of your cat. And no, it's not different, it's just like every other cat.
Any dog is better than any cat.
It's like the full moon or the changing of the tides. Let it be. Shopping is not sport. Anything you wear is fine. You have enough clothes.
