Here are some of them. Cat Inertia A cat at rest will tend to remain at rest, unless acted upon by some outside force - such as the opening of a can or the sight of a prey. A cat will move in a straight line, unless there is a really good reason to change direction. A cat continues to accelerate at a constant speed until he needs to stop.
Any pill given to a cat has the potential energy to reach escape velocity.
Any cat restrained for the purposes of administering a pill has the potential to reach escape velocity. Newton's Law of Concentration of Mass A cat's mass increases in direct proportion to the comfort of the lap she occupies. Newton's Law of Feline Gravity Manipulation Cats have the ability manipulate gravity, forming localised areas of strong gravitational attraction. This gives the impression of a cat growing heavier as it occupies a lap or bed. This is a linear effect with gravity increasing at a steady rate over time.
