Self-flushing, self-cleaning cat box

So now ya' gotta' compete with your cat for bathroom priority when nature calls? My marriage came with two cats. I quickly learned how badly they could stink up the place so built a privy for them....a two seater no less...in the basement. Basically it was a large box with a hinged lid and front entrance cloth door. It had a sensing device that knew when a cat walked in. It turned on a light and a fan that ran for a specific period of time and vented to the outdoors. It took them only a short time to get used to it. My family encouraged me to seek some sort of patent. All I really wanted was fresh air.
