Hiding the cat litter is really no big feat. All you need is a metal cutter and a steady hand to cut a hole, big enough for kitty to crawl in and out.
Ben says, “My girlfriend recently moved into my loft with her cat and her great dane. I needed a solution that would both hide the litter box from view and keep the dog out of the cat’s food and litter. I first bought the Ikea PS cabinet, which perfectly fits the alcove inside my front door. Then I used metal snips ($15 or so) to cut out a hole for the cat to enter through the bottom. This was easier than you’d think, because Ikea already has holes punched in the bottom for cords, so it was easy to start cutting. I filed the edges to make sure no metal splinters would harm the cat, and then covered them with red electrical tape. The cat took minimal training before she learned to crawl in and out of the bottom. The litter box is to the right, food bowls to the left.
