The canyon spreads out. It gives your cats several resting spots and a good run of wall to explore, and that elbow room does real work, cutting down on the standoffs and stress that lead to squabbles or marking. A more relaxed cat is a better housemate.The built-in cat bridge is the piece everyone gravitates to, a favorite for both racing across and lounging on. Whether your cats are tearing around or dozing, there is a spot in the canyon for it. It suits multi-cat homes and fits studs at 16 or 24 inch spacing.
