This cat safety net from Ferplast is designed for use on the balcony. Having a cat net keeps your cat from jumping off or falling from the balcony. Thanks to its transparent colour, you will barely notice this cat net. By measuring the distance between the upper edge of the balcony and the ceiling, you can find out which size you need. You can easily secure your balcony with this net, so your cat can access your balcony without any danger. The attachment line, metal hooks and anchoring screws are also included in the delivery. Warning: The nylon net is sensitive to temperature changes, which means it can expand or shrink. It can be tauter in the winter. If you\'re installing it in the summer, don\'t pull it too much. The transparent network is not very visible to birds. To keep them from getting entangled in the net, hang some strips of aluminium foil or fake birds to the net. Also, never leave your cat unattended once the net is installed.
