This takes the popular cat bridge and caps both ends with a hammock, so the crossing turns into a destination. Your cat can trek over and then sink into a soft spot on either side, which makes it as good for napping as it is for getting around. Hang it above a window or doorway or weave it into a full cat wall.Three lengths let you match the wall. The 34 inch spans five studs, the 50 inch reaches six, and the 66 inch covers seven, all on 16 inch centers. Longer runs simply add more room to explore and more places to sprawl.
