The Courandair window blocker allows you to keep your window in an open position that is small and stable enough to prevent your cat from passing through. You can thus ventilate your home with complete peace of mind.

The plurality of fixture positions offered by the Courandair window blocker allows you to create an opening slightly larger than the size of your cat, allowing it to enter and exit freely. The opening is held firmly, thus avoiding air currents from abruptly slamming the door.
