Well, Crow is still here. I guess when you feed and treat a girl well she sticks around. Joy and I each made a bed for her and they are now connected so she has an extra big sleeping area. Joy set up a folded towel for her to lay on with her two food dishes nearby, then I added a box with a folder towel inside and a soft nylon satin bag for her to rub against and enjoy.
We needed to put the garage down to comply with the neighborhood rules, so we decided to put it down almost all of the way, which made Crow scared so she ran away. When the garage stopped at her exact height she came back and smelled it then walked under it leisurely... like a happy cat. She did that a few times back and forth to inspect it and show off. Then she came back and loved on us a bunch again. Finally, we made her a snack of some skim millk with half-n-half, and turned off the garage light.
I suspect she'll be there in the morning.
