Windows that are tilted open can be very dangerous for cats because they can get pinched or injured. This fencing closes off dangerous openings and is designed so that cats can’t climb up it. Can be screwed or taped on to secure the window from all sides. If possible, the fencing should be mounted on the window frame with the included screws. This guarantees a long lasting secure protection for your cat. If it is not possible to screw the fencing on, it can also be adhered or taped, for example with help of TESA PowerstripsÂ®. We recommend you use materials to attach the protective fencing that can be easily removed at a later date. Colour: white, 1 piece (fencing for one side of window).
