Triple-secured fixing system: no breakthrough, no escape, even for strong and active cats. The widened hook-and-loop fastener ensures a firm hold on the window frame, while the high-strength adhesive provides long-lasting bonding. Dual protection for home and pet: this keeps mosquitoes, flies and other insects reliably outside while preventing your cat from breaking out. Suitable for most common : ideal for outward-opening and sliding with a frame width from 2.5 cm, whether wood, plastic, PVC or metal. For inward-opening , installation is possible only if a minimum of 4.5 mm remains in the closed frame to allow the net to be securely fixed. Extra tear- and scratch-proof mesh: specially developed for households with cats and other pets. Instead of thin standard fly screens under 75 g/m², uses a reinforced 320 g/m² polyester fibre with PVC coating. Tool-free mounting in just 2 minutes and easily removable: perfect for tenants and anyone who wants a non-permanent solution.
