Sunken design for curled-up comfort: This cat window bed is designed for cats that like to roll up into a ball to feel secure. Curling while sleeping helps protect the body and reduce exposure, enhancing safety and comfort. Foldable and space-saving: Mounts on a window or wall without occupying floor space. It folds upward for easy storage when not in use, making setup and stowing simple and convenient. This design can significantly improve interior space usage. Stable and secure: The main support frame is made of sturdy metal and resists bending, breaking, or warping with mounting hardware. Four strong suction cups provide reliable attachment with no manual installation required. Maximum load up to 40 lb. Zipper design and breathable: The cover features a zipper for quick on/off access. The breathable sandwich mesh fabric helps prevent moisture and stuffiness, stays refreshing and ventilated, and helps dissipate heat in hot weather. Use scenarios: - Sunny window naps: A single cat (up to 40 lb) can enjoy a warm, secure perch to nap and observe the outdoors. - Small spaces: Ideal for apartments where floor space is limited, offering a cozy perch without clutter. - Flexible placement: Easy to move between windows or rooms and store away when not needed.
