Mounted over a door with a traceless sticker and no drilling, this hanging cat climber turns unused vertical space into a four-tier playground. Five height settings from 58.5 to 61.5 inches fit different doors, and a plush perch plus a removable washable bed give cats places to rest. A jute scratching post and an included teaser ball invite scratching and play, while reinforced metal brackets and non-slip pads keep the climber secure. Each layer supports up to 11 lbs.
