This perch is a game changer for our rented apartment. No drilling, no suction cups that eventually fail it simply hooks onto the window sill slot and holds up to 40 lbs without a hint of wobble. My 14lb cat claimed it within minutes of installation and hasn’t left the window since. The 24×15″ bed is genuinely spacious and the plush orthopedic cushion looks really comfortable — he stretches out fully every afternoon in the sun. The natural wood and gray tones look smart and completely unobtrusive in the room. An elegant solution that takes up zero floor space.
