We leave the basement door open at night so the cats can get in and out. Our youngest son doesn’t like it when the cats are in the basement and doesn’t like the basement door open. There is a crawl space just inside the door where the cats sometimes retreat. Our son woke up and realized that Ether and Magic were in there. He sat down and stared at them because he wanted them to come out. This worked as well as you’d expect. Stephanie was able to lure them upstairs by offering treats. Meltdown averted.
