I heard from my brother-in-law and sister-in-law. These are the same ones that painted our room.
Cat circles really work. In one of my older posts I linked to an article about how cats are attracted to circles. They looped an electrical cord on the floor. Their cat crossed the room, entered the circle, and stayed there.
One of my readers was going to test this and post photos, but I don’t remember who. My relatives vouch for it working.
The next time you can’t find the cat, loop your belt or something on the floor and wait.
