Give your cats exclusive access to your home with the white electromagnetic cat flap. All they need to do is wear a cute little Cat Mate collar magnet around their fluffy necks, and they will surely enjoy the best of both worlds – the comfort of being indoors and the adventure of the outdoors. This cleverly designed cat flap can afford to be selective about who is on the furry guest list, as it uses a sensitive and quick-reacting circuit to accurately track who comes in and out. This gives you and your cats the assurance that you won't encounter any unfamiliar faces.
