Technology to help identify your pussy

It's very clever but I think that this is finding a solution for a problem that doesn't exist. As mentioned in the article, many cat collars have magnetically activated cat doors.

Car keys these days have microchips embedded in them, so do lightweight security tags in clothes shops, surely this kind of technology is a better and cheaper method?

The system they modified is a magnetic collar system.

The image recognition is to determine if the cat has anything in its mouth.  If it does, then the door remains locked, otherwise the door opens.

My bad

So it makes sure that your cat mutilates its prey outside, saving you from having blood and feathers all over the kitchen.
