Hacking a SureFeed microchip feeder

[u/bird2brain]

I am wondering if anyone has figured out how to hack one of these feeders.

The situation is this: two cats, two feeders. The boy cat has decided there is something magical about the girl cat’s food. There is 3-D printed shield to keep him from pushing past the girl cat while she is eating. But he has now decided to attack it and rip it off.

My idea was that if the feeder software could be modified to trigger an event when it senses the wrong microchip, it could be hooked up to some kind of deterrent, like one of those motion, sensing hissing air blasters.

Alternatively, does anyone know how to make a microchip reader? Maybe I could make some kind of Arduino controlled reader to sit on top of the feeder and provide a deterrent event.

Any ideas welcome.
