Cat Tax.

The key to winning over a cat is to pay the cat 'tax'. Whenever I enter a room with a cat in it, whether it’s just coming out of the shower, coming home from work, or just walking around the apartment, I’ll give the cat a little scratch. It lets him know that his presence is recognized, and that he's never ignored, not even once. It’s a small price to pay to have a cat who’s friendly and trusting.
