Law of Cat Inertia
A cat at rest will tend to remain at rest, unless acted upon by some outside force – such as the opening of cat food, or a nearby scurrying mouse.

Law of Cat Motion
A cat will move in a straight line, unless there is a really good reason to change direction.

Law of Cat Magnetism
All blue blazers and black sweaters attract cat hair in direct proportion to the darkness of the fabric.

Law of Cat Thermodynamics
Heat flows from a warmer to a cooler joke, except in case of a cat, in which case all heat flows to the cat.

Law of Cat Stretching
A cat will stretch to a distance proportional to the length of the nap just taken.

Law of Cat Sleeping
All cats must sleep with people whenever possible, in a position as uncomfortable for the people involved, and as comfortable for the cat, as possible.

Law of Cat Elongation
A cat can make her joke long enough to reach any counter top that has anything remotely interesting on it.

Law of Cat Obstruction
A cat must lie on the floor in a position to obstruct the maximum amount of human foot traffic.

Law of Cat Acceleration
A cat will accelerate at a constant rate, until he gets good and ready to stop.
