We ordered this cat box to replace one made of cardboard — I bought the cardboard one first just in case she refused to use it (something I wouldn’t put past her) — but she liked it so she received this up-grade. The legs and doors are solid wood, the rest is engineered wood, covered with a waterproof veneer. It was simple to construct, sturdy, and attractive, although I am not a fan of gray and wished there was a better selection of colors. 

The cat had no such complaints and it levels up the room. My husband began to lobby for a fancy cat box in his office, where out other two cats reside at night, so I ordered a different cat box enclosure for the other two.
