pass-through cat door to garage?
In our new house (under construction now), I'd like to create an "enclosed pen" for the litter boxes in the garage with a pass-through in the small mudroom wall (don't worry, it'll be safe so kitties can't actually get into the rest of the garage). Anyone else done this before?
I'm guessing I'll have to have a door on it (or 2 actually--one flap on each side of drywall) because of heat/cooling loss. I'd like to be able to clean the box from the garage side, so we'd hinge a lid (with lock).
