We installed this and our cat will not use it, it was hung on the wall in stud pretty high with the intention of purchasing the smaller Cleopatra perch  which would hang lower and provide a stepping way to the this one. This was not easy to hang, it is very heavy to hold up and mark where you need the screws to go. You have to use a stud finder to mark where those are and if you want at least two of the screw sets to go into studs you will have to drill two more holes in as the pre drilled holes are from left to right, 16 inches from the 1st to the 2nd, 17.5 inches from the 2nd to the 3rd, and 16 inches from the 3rd to the 4th set. To be honest, this was a huge pain. Once done, it looks beautiful on the wall, hope kitty likes it once he is able to jump up there and lounge. All in all, I would purchase it again. Go figure, I like unusual unique things:)
