The three cat litter boxes made of concrete and recycled wood were designed by the Standard Architects from Los Angeles. Although the three cat litters use the same material, they have their own characteristics and cats that satisfy different personalities.

The first one is called CATCUBE, which is a positive square. The front door can open the big door, and the back window can be peeked. A mezzanine was added inside and it became a duplex.

The second one is called CALIFORNIA CATCUBE. The first one is a short, flat rectangle with movable louvers on both sides. The roof can be used as an outdoor terrace for the sun.

The third model, called CATOSPHERE, is a cut-out sphere with swinging wood louvers in the middle, a soft sofa inside and even a light on the top.
