Is it a full moon or what? When I lived in CT, I used to have to take "kitty inventory" every night when I got home from work because my oldest female, Mollie Rose, would BOLT the minute I opened the door and I was too tired to notice it. Fortunately, both the back and front doors lead to a hallway. But there have been times when I'd get up in the middle of the night and hear a cat crying out in the hallway. At first I thought it was someone else's cat (my neighbor's cat was ALWAYS getting stuck in the hallway). I'd open the door and there she would come strutting in, looking at me like "I meant to do that and what took you so long to open the door anyway???!!" MooShoo did the same thing twice. But he now thinks twice when the door opens because he knows how cold the stairway is.
