Summary

  • An automated cat door, known as the Cat Valve, has been created by hacker [Rkramer] to prevent unwanted animals, such as rodents, from entering their house.
  • The device works by using an IR sensor connected to a Raspberry Pi 4 to detect when the cat is heading out through the exterior cat flap.
  • When this happens, the Raspberry Pi fires up a motor connected to a lead screw, which closes the flap between the buffer zone and the house, offering the cat a space of safety, but not allowing any prey to enter the house.
  • This is a useful solution for anyone who has issues with their cat bringing home animals they have hunted, and while it may seem cruel to some, it avoids the hunter-cat and its prey from entering the house.
