Window Suction Cat Perch and Sisal Scratching Post Set

Give an indoor cat a spot in the sun without drilling into a wall. These wooden shelves and sisal-wrapped scratching columns stick to a window or glass wall with suction cups, so a cat can climb, lounge and scratch at eye level with the view.

Choose from single pieces and combined sets. The range runs from a lone jumping platform or scratching pole to a lying table with a grab column, a hammock-style lying bed, a clear space capsule nest, and larger three- and four-piece arrangements. Several sets go up without punching holes, and the scratching column uses a strong suction mount. The sisal wrap gives claws something rough to work on, and the wooden frames carry the weight of the shelf.

Before you order, pick the glass you plan to use and check there is room for the set you want. A lying table measures about 16.5 x 10.4 x 8.2 in (420 x 265 x 209 mm), and a single grab column is about 19.4 x 7.1 x 5.8 in (493 x 180 x 148 mm). The space capsule nest is meant for cats under 22 lb (10 kg). Suction cups hold best on clean, smooth glass, so wipe the surface first and recheck the grip now and then, especially after temperature swings.
