Cautious optimism, here.
I have succeeded in washing clothes, and learned that the secret to overcoming claustrophobia is to concentrate on the task at hand. So far, so good.
I have placed a glass shower door across the cat door. The cats will just have to get used to asking to go out, for a while, anyway. Maybe forever.
I mean, once an armadillo gets a foot in the door, what's next? Raccoons? Possums? Small dogs? Rats?
We shall see what the morning will bring.
