this MeowTown kitty window lounger attaches to the window and holds up to 14 pounds. It uses suction cups to attach to the window. I have a similar, if not the same product and I’ve included pictures of my cat sitting on this perch. I would recommend following the directions. I have found that it does work and my cat enjoys it. This style also folds up against the window to allow you to close the blinds..so you can close your blinds when the perch is not in use. Offers considered. Bundle to save more. Questions?
