Do you want to give your cat more freedom – without compromising on safety? A cat enclosure is the ideal solution for relaxed hours outdoors – with a good feeling. Because you know: Showing responsibility means acting proactively.

Many cat owners wish to provide their cat with access to fresh air – without compromising on safety. A cat enclosure creates exactly this space: protected, reliable, and adaptable to your living situation.
Whether on the balcony or in the garden – a protected outdoor area gives your cat the opportunity to observe the surroundings, enjoy fresh air, and move freely – without dangers from roads, other animals, or uncontrolled excursions.
The cat enclosure on the balcony is particularly popular, as it can be easily implemented even in the city or in apartments without a garden. With little space, a safe outdoor area is created, which gives your cat new impressions and you more serenity in everyday life.
Especially for indoor cats, safe outdoor access is a welcome change. Many behavioral problems such as restlessness, boredom, or lack of exercise can be reduced if cats have protected access to the outdoors. An enclosure offers this space – structured, safe, and visibly confined.
Our enclosure solutions are designed to be functional, unobtrusive, and flexibly applicable. You can choose the suitable area for your home and offer your cat exactly what it needs: more variety, more exercise, more freedom – with simultaneous protection.

On lawn or soil, you fix the enclosure with ground anchors that grip into the profiles or base plates – this keeps everything stable even in wind. On the terrace, non-slip rubber feet work in combination with weighted base plates or plate weights; drilling is not necessary. On the balcony, you use drill-free clamping or tensioning solutions on the parapet or railing that can be removed again without leaving any residue. Optionally, an additional wall support provides even more stability without damaging the building structure. With ALUSTECK®, you choose the right feet, anchors or clamps depending on the surface and stay compliant with tenancy law.
