Startling noises

Standing at the kitchen sink, I hear a rumbling shudder.

What in the world?

No heavy trucks drive in this neighborhood.  No delivery trucks start rounds at 6 AM.

Did the closet rod collapse upstairs?  Again?

Next, I hear a long scratching sound.

Sigh. It's Bogie.

First, he planted his shoulder against the hall wall with a resounding thud.  Then he dragged his head and shoulder along the length of the wall, his collar scratching against the drywall.

He's like a cat rubbing itself against the furniture.  Only ten times bigger.
