I usually FReep with my keyboard on my lap, but I set it down if I am just doing a lot of reading. My cat lives for those times when he can jump up on my lap. He knows better than to try it if I have my keyboard in my lap, but he will still sit next to my chair and give me dirty looks and let out a disgusted meow or two.
I can't hear him anymore. Maybe I could wire up a key on each side of the door and one at the food dish
that would throw up a message window on the monitor. "Let me in." "Feed me." Naw! He'd just abuse it.
