Strange things your pet is attracted to

I don't mean to bump such an old topic but I just had to share my own experience with Oscar, my kitty. He is very strange and seems to be fixated on video games, for example, if I'm playing my 3ds he will watch the screen and when I am playing World of Warcraft he will follow the characters as they move on the screen. I play computer games on a large HDTV so he will go back and fourth from side to side on the screen.
