A secure, custom-built steel enclosure — or a protective mesh — for your exact window or balcony. Built by hand, one at a time. No drilling, no guesswork. Just fresh air, a happy cat, and peace of mind.
Whichever fits your window or balcony, both are welded steel — handmade in Poland, measured to your exact space, and shipped with a real person on the other end of WhatsApp.
A removable steel enclosure that fits your window frame and extends outside — so your cat can sit, sniff, and watch the world in complete safety.
Heavy-duty steel mesh that covers your balcony railing or window opening — keeping cats, dogs, and kids safe without blocking the view.
A catio, a wraparound enclosure, an odd-shaped balcony — if it's steel and it's for your cat, chances are we can make it. Send us your idea on WhatsApp: we'll sketch a design, quote a price per metre, and tell you honestly whether it's something we can build.

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.
A welded steel grid — not fabric, not plastic. Built and tested for climbers, escape artists, and everything in between.
We measure your exact window or balcony and build to match it precisely. Tolerance of ±5 mm.
No drilling, no marks, no landlord worries. Fully removable when you need it.
We stay with you from first message to final install — and beyond.

Ask us directly →The Cat Balcony (899€) is a full steel enclosure that extends beyond your window frame, giving your cat a real space to sit, walk, and lounge outside. The Protective Mesh (279€) is a flatter steel grid that covers a balcony railing or window opening to stop falls and escapes — no extended space, just a safety barrier. Not sure which fits your setup? Send us a photo on WhatsApp and we'll tell you.
No, for either product. Both are secured using steel brackets that grip the window frame or railing — no drilling, no damage, no marks. Safe to install in a rented flat, and fully removable when you need it.
We provide a short video guide for both products showing exactly what to measure. All you need is a tape measure — it 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.
Both products are welded steel — not fabric, not a plastic kit. The Cat Balcony is tested to 40 kg of load capacity, including dynamic testing at 70+ kg of human weight. The Protective Mesh is tested to hold firm against a cat, dog, or child leaning their full weight on it.
Cat Balcony from 899€ and Protective Mesh from 279€ — both include the custom-made steel piece, mounting hardware, video guides, and full support before, during, and after delivery. Final price depends on your exact window or balcony size.
