Pawhut Catio Playground Outdoor Cat Enclosure, Wooden Cat House with Weatherproof Roof, Shelves & Bridges

The directions are basically a pic, and not in the best order for construction. There are no measurements on parts, and it is not a free standing structure, but three sided and needs to be mounted/screwed into a smooth, brick/wood wall. One needs to also pre-drill the holes in the piece of wood section being connected as well as one needs to use a lot of upper body strength to manually screw on all the screws, unless one goes out and buys a 90° angle driver. However, it does fit the requirement that I can stand up in it and maybe put a chair in it for me to join my cat when it is outi in the Catio.
