Aaww Trixie, what a gorgeous lady you are! And so smart. It must be a tuxedo thing
My first kitty was a tuxedo like you. He, too, used to sleep on my bed at night. When I left home for University I was sad I could not have him with me and I thought he would "forget" me. But everytime I was back, it was just as if I had left 5 min earlier.
