I think some guy did a HackaDay or Instructables about this a few years ago using Arduino. He got it to recognize his cat’s face to keep out other neighborhood cats. But to give the software enough time to recognize the face, the cat had to go through a 3-ft tunnel. Our cat door is built into the real door, so I can’t attach a tunnel to the outside. But our problem isn’t the wrong cats coming in. What I need is to detect if the cat has something in its mouth like a rat, which they love to bring in alive to play with and immediately lose so I have to root them out. Our cats are dumbasses.
A few years ago I saw someone just simply checking for a cat head silhouette. Was enough to deter other animals and also worked to recognise if the cat had caught something.
We have a cat flap that detects the RFID chip in her shoulder. It seems to be broken since a few weeks. But our cat (and not the stupid neighbour’s cat) can open it anyways with a little prying with her claw. But luckily that doesn’t work as well when she has an animal in her mouth. So we will probably leave it broken.
Silhouette sounds like an interesting method, although I’ve never tried to figure out how to test with and without rat in mouth. Probably would just have to try it in practice.
