Molly is the instigator. Once she's awake - she gets just about everyone up to go potty/bark outside. Once she's gone out, she goes right back to bed. Happens almost every night.

Kirby would rather stay in, but in my book (and since I'm awake) if one goes out - they all go out.

Hope Molly thinks twice as the weather gets colder. I hate getting out of a warm bed at night.
