Although I heartily agree with the first suggestion you received "give up work" - here is how I solved my Rascal lap problem.

I have a chair right next to the desk that the computer sits on.

I recently bought Rascal a little bed. Funny how they just know......he loves it. So it is easy to transfer his heavy body into the bed and his feelings are not hurt when I have to get back to work.

I have tried typing while he was on my lap - and then I would see what I just typed because I didn't realize my fingers were on the wrong keys - pretty funny.
