Litter Box plumbing

Pregnant women run the risk of contracting a disease known as toxoplasmosis, which in turn can harm or even kill their unborn child. One of the main causes of this is coming in contact with cat poopie. In my relationship, and from what I hear in many others too, I have made it clear that I don't want anything to do with cleaning up after the cats. I’ll feed and pet, but I didn’t want the cats to begin with. My wife found a “buy one get one” sale at the local shelter and couldn’t resist the urge to get 2 cats…ARGH Not only that, but she “rescued” a kitten from the streets out of the goodness of her heart. The only time in our relation I have ever cleaned up the litter box is when she was pregnant with our children, for fear she might touch the dreaded poopie and kill the children. Oops, well, back to the idea.
My idea is to have a detachable chamber built into the base of the litter pan. After about a day or two of continuous use (or how ever long it take to fill up, my cats seem to have over active colons though) just step on a pedal and the top part (which holds the litter) slants to let the litter slide into the bottom compartment.

Once the litter and it’s debris is in the bottom chamber just lift the empty top part off, set aside, and just take the bottom part off to the trash bin. The bottom part could be dispensable or could be made to hold pre-sized plastic bags that can be tied off and thrown away.
