I can see what this gadget is all about. Pop a microchip onto your kitty and the little one controls the cat-flap. Be gone all you other neighborhood cats! See, the cat flap detects if it is your cat (via microchip) and only lets in your cat.
You can even set an auto lock system; no cat exits at night where the ‘gate to great outdoors’ is only open during the day.
I thoroughly understand the merit behind such a system. We had a harrowing experience when a wandering cat from the area strolled in and picked a fight with the little kitty of the house.
