We call it "The Exercise House"

This long hallway bisects the house. Bedrooms on the left, dining room and kitchen on the right. The dining room and kitchen connect to each other, so the dog and cats (and crazy humans) can case each other in circles from kitchen through the hall, into the dining room, back into the kitchen, down the hall to the living room, through the dining room, back into the hall and into the kitchen...

You get the idea. It tires me out just describing the melee to you.

No.
The animals have not realized there is no traction on hardwood floors, as opposed to running on carpet. They're like furry cartoons who spin their legs in place before they finally take off. Pretty darn funny.
