I'm not sure if this is enough for demanding cats, but I used to type with a small dog bed directly in front of me and my keyboard behind it, so that I'd work typing with my arms around my elderly chihuahua every day. She seemed to like it a lot, and she basically had my attention every time she stirred.

I also felt that it was probably good for me for her to break my flow and demand my attention every now and then. It helped remind me to get up and stretch and be human better than I otherwise would have done.
