I'd like to avoid some obvious problems, like water in the walls. So
either make a channel out of backer board or find about a 6" tube.
Slope it down toward the outside so it drains and has a bit of wind
blocking.
Those are my ideas. I don't always have good ideas. Something else?
The commercial cat doors have not been holding up for me, but they
get a lot of use.


I built mine in a 10" wide board that fits under the partially-closed
window. If the cat door ever needs to go away, I'll just raise the window,
remove the board containing the cat-flap, then close the window.

Oh, there's a screw in the window frame to prevent the goblins, squints,
mopes, do-bads, stink-eyes, etc., from using the cat door contraption as an
entryway.
