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...

Constant fans are sucking outside air into your house. Could be part of your Heat/AC efficiency problem mentioned in your post. A timer to run every 10th minute would be a simple improvement.

A lot of newer building codes require fans to be constantly running anyway due to the other part of the building codes requiring high r-value insulation.
