Several years ago a friend gave me a video called "Video Catnip" or something like that....it was a closeup of a birdfeeder and you could see and hear all the birds as they came in to eat. My kitties at the time (who have both since passed away ) sat absolutely still in front of the screen for a good 90 seconds, swatted once at the screen and then they seemed to decide it was one of those 'silly people things' and lost interest forever....
