This is truely living the dream, well done mate! It is indeed crazy that cabinetry costs the same as the technology.

How does the cat restroom exhaust work? Always on or does it have a sensor?

Do the cat doors prevent sound getting into the kids' rooms from the living room?

The cat room fans are standard bathroom fans. At present we just leave them on all the time -- you can see the switches taped down in the photos. I suppose it might be a good idea to rig up a sensor...

Might be able to use a flipper zero as the sensor, if the cats are chipped. Then you'll have data to catch any unusual usage, like a urinary blockage, before it becomes a serious problem! At that point you're a smart switch and Home Assistant script away from fan control.
