Abstract: The invention comprises a perch for a pet, usually a cat or ferret, made up of a shelf-like member with attached tabs that connect by gravity under a window sash and an adjustable, telescoping, support column below the shelf-like member to allow the shelf to be adjusted and stabilized to the proper height to allow the bottom edge of the shelf-like perch to rest on a conventional window sill. All of the exterior parts are covered with a fabric or constructed of a material such that the pet is encouraged to scratch on the device and, thus, discouraged from scratching on the humans' furniture.
