Slowly, very slowly, blink your eyes while taking slowly to your cat. If you wonder why a cat seems to be squinting at you, it's not that they're giving you a negative look - the stink eye - They slow blink and squint at you to show affection. Talk to them in a different voice than when you regularly talk. Make your "I'm Talking To You" Kitty-Voice different than your normal voice. It becomes more clear to them when you're addressing them. Say their name a lot when talking to them. Hi, Mr Kitty. How are you? Does Mr Kitty want something? Is Mr Kitty hungry? I'm going to get a treat for Mr Kitty, because Mr Kitty is a good kitty. It helps them to know that the sound "Mr Kitty" is referring to them in some way. Not that a cat necessarily knows their name, but they know that a certain sound "Mr Kitty" refers to something they should be involved in. It's for them, something about them, related to them, etc. Slowly pet them on the top of their head with your thumb while you place your hand on the back of their head/neck, and then pet the back of their neck with you fingers. Always slow strokes, no matter where you're petting them. Pet them not like you pet a dog. And when petting them, talk slower and say their name a lot.
