FCATS: My Quest to Outsmart Cats with Code


So, you know how some people spend their free time knitting, doing CrossFit, or collecting rare stamps? Well, I decided to build a system to scare away cats. Yes, really. It’s part AI, part DevOps playground, part “please don’t ask me how I got here.”

Why am I doing this?

Let me introduce you to FCATS: (a) Fully Configurable Automated Tracking Software

  1. Because cats kept showing up in places they shouldn’t: They leave things in the garden that they should rather dispose of in the litter box, or steal fish from the pond that don’t belong to them.
  2. Because I needed a fun, hands-on project that mixes computer vision, monitoring, and automation.
  3. Because “Katzenschreck” just sounds too good not to be a project name.


The result: a full stack of open-source tools that combine AI object detection, monitoring, and benchmarking into one gloriously over-engineered cat deterrent.

Katzenschreck - functional Architecture. The ip camera records a cat, connected to a Raspberry Pi, that runs the Computer Vision inference. If a cat was detected, the sprinkler can be activated via home automation. Pictures are stored in a database and can be observed via a surveillance software.

Why Katzenschreck Stands Out 🚀

The unique selling point of my solution is that it runs headless on small edge devices while integrating cutting-edge models like YOLOv12x. This makes it easy to deploy in multi-location and multi-camera setups. Unlike more user-focused tools like Frigate, Katzenschreck is designed to fit into existing IT infrastructure — following enterprise-grade architecture principles with DevOps workflows, Docker containers, and Kubernetes clusters. In short: it’s not just a tinkering project, but a system built to scale.

It’s not only about showing off AI tinkering, but also CI/CD pipelines, monitoring setups, and how to package weird ideas into working systems.


Stay tuned, because the cats certainly will.
