The switch location is such that it only triggers when the door is fully open, make false positives very unlikely. But possible I guess. Reliability was the main design goal here, and several years later, I can say that this was achieved. If the only goal is to know for sure where the cat is, or if you have more than one cat, you could always place a raspberry pi or a security camera indoor side and trigger recording whenever either switch is activated. Synology Surveillance Station for example can be triggered via a web command. If I were to build version 3.0, I would consider adding a Jetson Nano to actively recognize and classify each cat passing through the door...
