When I first spotted this on moderncat, I thought it was a prototype for a futuristic creation. However, much to my surprise, the Litter-Garage ($180) already exists. According to the manufacturer's website, it only takes an hour of installation (provided you have an existing cat door) and is a safe way to stash the stinky box in the garage without worrying about a feline taking a nap under your car. And how well-prepared you'll be come clean up time – there's space for a scoop, waste bags, and even antibacterial handwipes, too. Kitty's poo stays out of sight, while your lil kitty-poo stays on the top of your mind.
