The solution: We looked into other very expensive and sometimes no-so-practical solutions. Inspired by some Ikea Hacks ideas, we went to the store determined to find a solution. We came across the Fullen Sink Base cabinet with two doors and aha! we found what we needed (Just never used the legs). The opening is perfect for our our cats. As it is not very high, we got disposable litter boxes at Petco. Cleaning the litter box is now a breeze, all there is to do is to open the two doors wide and take care of business without complications.
