We had 2 shop cats where I worked many years ago. The female tabby (w/a little Siamese) used to love laying on the old CRT monitor. I think that monitor put out a lot of EM radiation because of the whining sound. She lived to 21.Our cats are not happy with us. We swapped out my wife's computer with a new one. The old one was 19 x 7-1/2 inches, but the new one is only 12 x 6-1/2 inches. They can't stretch out to nap on it any more.
