With the hot weather we’ve been getting lately, and no AC, we usually leave the front door open until I hit the sack at night. (A security gate at the entryway makes this possible.)
So last night I shut 'er down around 12:30. Wake up this morning to the sound of a cat wanting out. We don’t have a cat. Sure enough, there’s a big gray cat sheepishly sitting by the front door. I don’t know how he managed to avoid detection all night.
