This spoken to our adorable little cat Emme who insists on sitting on my lap while I'm at the computer which in and of itself is not a problem. It's the way she does it. First she lays lengthwise and my arms are just long enough to reach the keyboard. Then she gets up and turns herself around and usually some part of her ends up ON the keyboard. Last but not least when I try to move her she flings herself off my lap muttering obsenities.
