I just recently discovered that our cat has an amazing sense of perception. When I'm typing on the keyboard, she is very careful not to step on the keys when she's on the countertop. But when the computer is off, she walks on them with impunity.

She also has a habit of sitting on any book or magazine I am (from her POV) staring at, which is a form of opposite behavior of the above attitude with the keyboard, because she does it while my attention is focused on reading it. Hmm, perhaps if I pretended to be typing on the book, she would avoid it (but only as long as I kept 'typing'). Maybe I could just drum the fingers of one hand a little on the book everytime she starts to approach it... -bit
It's just her way of saying your spending way too much time looking at something when you could be giving her the attention. Every time I get a phone call my dog and cat get right up in my face telling me I should be talking to them.
BTW, how did the silicone spray work for your keyboard?
