We have four cats and three of them just love being on my computer desk. They will normally curl up on my office chair if I am not there. Sometimes they sit up and look at the screen saver, whatever it happens to be that day, batting at the moving pictures. Sometimes when I am working they sit on the foot stool that is beside my desk and watch what is happening on the monitor. Obviously they can see the changing shapes and the movements. At other times they get right up on the desk and try to catch my hand while I move and click the mouse. If I am not at the desk and they are on it, they sometimes curl up right around it. I don't know what the attraction is there. When we see them sitting in the chair or on the desk when no one is there, we say they are on the Internet sending mEow-Mail. (Yes, I just heard your collective groaning...)
