- Abrasion and tear resistant nylon with UV protection: high strength material resists cat scratching and outdoor wear, and sun exposure won’t easily cause deterioration or fading for long-term use. - Uniform dense mesh: 1 inch mesh ensures cats cannot break through while maintaining ventilation and natural light, helping air circulate indoors and outdoors and providing a barrier against rats, pigeons and other larger animals. - Double protection edges: thickened mesh cords seal the edges to improve overall stability, preventing scratching, biting and accidental escape or injury when pets are active on the balcony. - Easy installation: includes nails to attach to the bar with a hammer in small steps, ensuring a firm fit that won’t be blown away by wind or squeezed through by a cat. - Practical use scenarios: create a safe outdoor space on a balcony railing for indoor cats; cover balcony or window openings to deter pests while keeping pets secure; install on patios or garden areas to prevent wandering and protect pets during outdoor time.
