The Sunroom Stretch: Custom Freestanding 10×4 Catio With 8 ft Window Tunnel

Let your cat explore, lounge, and play across connected spaces built just for them — right outside your window. The Sunroom Stretch is a Custom Freestanding 10×4 Catio With 8 ft Window Tunnel, thoughtfully designed to blend open-air freedom with cozy protection.

This unique custom catio setup features two connected spaces: a freestanding catio measuring 10 feet wide, 4 feet deep, and 8 feet tall, and a window catio enclosing only the bottom half of your window. Linking them is an 8-foot-long tunnel, giving your cat the freedom to move safely from the indoors to the outdoors — through a window access point — while enjoying sunlight, fresh air, and stimulating views.

Built from pressure-treated lumber and enclosed with 1” x 1” black PVC-coated welded wire, The Sunroom Stretch ensures lasting durability, protection, and a clean, modern look. The freestanding catio includes a deck base for added comfort and stability, while its classic ribbed steel metal roof offers partial shade and weather resistance. Both the window catio and tunnel are roofless, allowing sunlight and breeze to flow freely through these connected spaces.

Inside, your cat can climb, stroll through the tunnel, and relax in the open air — all while staying completely secure. With two human-access doors (one on the tunnel and one on the window catio), cleaning, maintenance, and bonding are effortless.
