Our cats absolutely love these scratch octahedrons. I previously bought from a local pet store, but they were nowhere to be found, after our cats had destroyed the one we had.So I was very happy having found them again, at Wayfair.I cleverly bought two this time, as they usually fight over access. Which brings me to the first issue, as they fight over who gets to stay, means that the octahedron sides falls apart. I tried glue (but thats messy and leaves residues), so I tried binder clips (removing the handles after). Both methods seem to work fine. Furthermore, the scratch pads were poorly cut, making it impossible to properly fit the sides together. Had to use a bread knife to trim the scratch pad edges back. In conclusion, had the scratch pads been properly cut, and the sides wouldnt fall apart, i wouldve given five stars.. Hulten. Portland, OR. Sat May 18 2019
