I LOVE this idea - we have two cats that intimidate each other when they see the other using the box, one cat that is a standing pee-er, and a dog who wants all the poop candies with pee-flavored sprinkles. We've tried every high-sided, covered box that we have been able to find but still have issues because of the standing pee-er. Her urine always gets in the gap between the cover and the box, proceeding to leak all over the floor. Gross! I think this will be a perfect solution. Thanks for the instructable! Question: Did you need to file down the cut plastic at all? ...is it sharp?
