Ok, so your typing away and your cat is walking on your desk, crossing in front of you doing the purrrr thing, and of course your cup of coffee ends up across your keyboard, and "lights out"!
Cats have a way of stepping on things that can really mess up whatever we are doing. Tiger likes to walk on my answering machine and play havoc with that. Sometimes he deletes messages. Wonder if he knew something I didn't. hmmmm.
Mine was when my kitty ran on the entertainment center and almost knocked my Wii over. She only got the censor on the top, which is pretty durable, I might add. lol
