Cats are very independent animals. They're very sexy, if you want. Dogs are different. They're familiar. They're obedient. You call a cat, you go, 'Cat, come here.' He doesn't come to you unless you have something in your hand that he thinks might be food. They're very free animals, and I like that.
You automatically are trusting because not only is the person a friend, they are so incredibly gifted that you know someone is going to be able to hit the ball back to you across the net.
I'm still astounded by some people's reaction to things I consider quite normal.
