One product. Made for your window. Built for your cat.
A removable steel cat window box that fits your window frame perfectly — extending beyond the window so your cat can sit outside, feel the breeze, watch the world, and simply be. Built by hand, one at a time, from galvanised steel with a powder-coated finish. The same process used on cars. Built to last decades.

We're BalconyCat — a small team based in Poland, making handcrafted steel enclosures and protective mesh for cat owners across Europe and worldwide. Every product is a welded steel grid, not plastic clips or flimsy fabric netting.
After installation, test it yourself: push it hard, pull it sideways, hang your full weight on it. Ours are tested to 70+ kg of dynamic human load. Your cats can jump, hang, and lounge on it for generations.
Still have questions? We're real people — just ask us directly. We respond fast.

No. The enclosure is secured using steel corner brackets that grip around the window frame — no drilling, no damage, no marks. It's safe to install in a rented flat. Fully removable when you need it.
We provide a short video guide that shows you exactly what to measure and how. All you need is a standard tape measure — the whole process takes about 3 minutes. If you're unsure, send us photos or a short video on WhatsApp and we'll check your measurements for free.
The enclosure is a welded steel grid — not fabric, not a kit with plastic clips. It's tested to 40 kg of load capacity, including dynamic testing at 70+ kg of human weight (jumping, pulling, hanging). After installation, test it yourself: push hard, pull in every direction, put your weight on it.
Yes. We can powder-coat your enclosure in any RAL colour at no extra cost. Some custom colours may add a little extra production time, but we'll tell you in advance.
Yes. We offer a mosquito net panel as an optional add-on. It attaches to the outside of the enclosure with adhesive tape — keeping insects out while allowing full airflow.
