My kitties absolutely adore this S77C-BG model. The 77 inches is no joke, it toweres over everything in the living room. Only reason I gave 4 stars instead of 5 is because the box was super heavy to drag inside alone and one of the scratching boards was a bit frayed at the edge out of the box… i just trimmed it off though. But once it was up?? Total cat paradise. They love the cave part and the hammock is surprisingly strong.
