Two things to note about cats:
1. Have you ever felt your cat's purr? You know they really love you, when they trust you enough to let you put your hand on the vulnerable spot at their throat, where you can feel their purr rattle and dance.2. When I smile at my cat, she turns her ears to face me: like she can hear my smile. It makes her look like an owl. I like the idea that a smile is more than just a visible thing, that it might have a sound too.
