Cat in a box (solution to my cat "helping" use the computer)
This is my son Connor. He often wants to "help" me use the computer. I just set up a box for him on the desk. It has worked really well, instead of trying to sit on the mouse pad or lie on the keyboard I encourage him in to his box and he just hangs out until he gets sleepy.
Cats bury their feces to cover their trails from predators.
