My cats have always raced the dog to greet me at the door. I think it depends on the cat whether they show enthusiasm when you come home.

My current cat has developed her own form of cat x-games. There is loft-diving (jumping out of the loft onto unsuspecting victims, usually either myself or the dog), dog bed surfing (where she runs full tilt and leaps onto the dog's bed and slides half-way down the hall), and her new favorite, shadow chasing. Kaylee is never boring or bored...
