The Square is a nice compact complex. Its only 34x34 and has two lounging areas, a scratching post, and a thought provoking path to get up and down the complex. Since this is part of our Cat Mod collection, you can set it up using the step by step instructions to create the layout weve come up with or since its a modular system, you can also build it many other layouts to perfectly fit your space This piece is mounted along three studs, spaced 16 apart. (If your studs are spaced differently, let us know before ordering and, if necessary, well send you a custom setup accordingly for an additional fee.) The Square comes in your choice of Onyx, English Chestnut, or Unfinished wood. All sets will come with the canvas color of your choice and Nickel mounting hardware. Includes: 106 Canvas fabric 18 Sisal-lined escape hatch 18 Solid shelf 3 Mounting planks 1 Floating sisal post Would you like to add a Feeding Station or a planter onto your wall-mounted setup? Check out our Cat Mod Add-ons. Standard Dimensions: Total Width: 34 Total Height: 34 Depth: 11 (This measurement is for the layout in the primary image for the package. Because the Square complex can be used to put together so many different layouts, there are also a lot of different measurement options.) We use solid wood for the mounting planks and thick heavyweight canvas for the hammock. Brackets come attached for easy installation. All of our furniture also comes with screws for mounting. Were excited to introduce the Cat Mod, the second generation of our fabric cat complexes. When creating the Cat Mod, we made sure to maintain all the positive aspects of our original collection of cat hammocks and complexes, such as strength, appearance, and quality, while also adding some new and exciting features that elevate it from the original collection. Our new patent-pending system has a lot of great advantages, including its washable cotton canvas. This system allows you to remove the fabric from the structure without having to take down any of the mounted planks from your wall. Not only will this make cleaning a breeze, but it will allow you to continue to build the structure at your leisure. This gives you the option of switching out canvas fabric colors down the road. Another great feature is that these complexes are modular; you can build any design you dream up. The Cat Mod system is like the building blocks you used as a kid in the sense that we created it to allow customers to build on or rearrange the pieces for limitless design options. We will be including schematics to build some standard configurations, but we hope to inspire you to come up with your own unique complexes!
