Petscosset 71-in Wooden Catio Outdoor Cat House, Gray

In short, great catio. There is a main door (open in the second screenshot) for human entry, and there are two small cat-sized doors at the bottom on either side (you can see the white frame close to ground in the second screenshot); This allows cats access to the rest of the patio if you so desire. Packaging came in two separate boxes. Box 1 had the instructions. All the panels had pre-drilled holes. There is a short assembly video on the vendor's website as well. The instructions also include instructions if you want to assemble two sets, which could be back-to-back, giving a bigger cube enclosure, vs side-to-side which gives an elongated enclosure. There is a removable panel in the back in case you want to do the back-to-back two set assembly to allow cats to jump from one set to the other. There was one issue in the instructions. On the page where you install panels 11 and 21, there is a hand-written annotation which instructs to swap 21 and 11. however the correct way is not to swap those two panels. this is to ensure that the bench that will be installed has three equally distanced supports. Other than that it was easy to assemble. It took me 3.5 hours of easy going effort including unboxing and trash removal. There is a lot of extra screws specially in case if you buy two sets and want to screw them together.
