We’re BalconyCat — a small team based in Poland, making handcrafted cat window enclosures for cat owners across Europe, the UK, and the US. Every enclosure is a welded steel grid fixed to a steel frame. No plastic. No flimsy mesh. No aluminium.
After installation, we recommend you test it yourself: push it hard, pull it sideways, hang your full weight on it. If you’re worried about breaking it — that’s not a BalconyCat. Ours are tested to 70+ kg of dynamic human load. Your cats can jump, hang, and lounge on it for generations.
A welded steel grid — not fabric, not plastic. Your cat can sit, jump, hang, and explore without any risk of falling. Built and tested for climbers, escape artists, and everything in between.
No off-the-shelf sizing here. We measure your exact window frame and build to match it precisely. Tolerance of ±5 mm — that’s it. Your window, your enclosure.
No drilling, no marks, no landlord worries. Steel corner brackets grip the window frame securely without leaving a trace. Fully removable when you need it.
We stay with you from first message to final install — and beyond. One person, one conversation, real answers. We’ve never left a customer stuck, and we don’t plan to start.
Still have questions? We’re real people — just ask us directly. We respond fast.
Ask us directly →A cat window balcony is a steel enclosure that mounts to your window and extends outside, giving your cat a safe, open-air space to sit, sniff, and watch the world. Ours are made from galvanised steel with a powder-coated finish — the same process used on cars. No plastic, no aluminium, no fabric. Just solid, welded steel that handles rain, sun, and curious claws without complaint.
The BalconyCat enclosure is designed for casement windows — the kind that swing open. If you have a different window type, get in touch and we’ll help you figure out the best solution. When in doubt, just send us a photo.
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 before anything starts.
Follow the video guide, use a proper tape measure, and send us your photos to confirm — and you won’t go wrong. We review every measurement before production begins. If there’s ever an error on our side, we fix or remake your order. No arguments.
Galvanised steel with powder coating means no rust, no warping, no degradation. We’re confident the enclosure will outlast 10+ years of daily use — and likely several generations of cats. In the rare case that wing-nut fittings show surface rust, replacements are available at any DIY store.
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. If you’re afraid of breaking it — that’s not a BalconyCat.
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. Standard colour is available faster.
Yes. We offer a mosquito net panel as an add-on. It attaches to the outside of the enclosure with adhesive tape — keeping insects out while allowing full airflow. Just mention it when you get in touch.
We ship across Europe (typically free), to the UK, and to the US. UK and US delivery costs are calculated per order — just ask us for a quote before committing. Delivery is invoiced separately at time of dispatch.
