We all know that pets keep to their own schedule. So let me paint a picture of my house at night.
We baby-gate the door, so if the dog is going to do damage (aka, pee everywhere), she does it in our room. Needless to say, there wee wee pads. The cat has free roam of the house.
Everything is usually quiet until 3:30 or 4am. That's when the cat comes in. It's breakfast time, damnit (according to her). Now she will use a variety of methods to wake us up. And by us, I mean the Spousal Equivalent. She'll bite him, or walk on his face, or simply stare at him (I think trying to communicate telepathically).
She loves to so this on Saturday mornings.
Now, if it's not the cat, the puppy LOVES to bound up during the wee hours and lick the Spousal Equivalent's face. That happened yesterday.
Strangely enough, I get left alone.
Though now I tempt my luck!
