A cat's irritation rises in direct proportion to her embarrassment times the amount of human laughter. A cat will drink his weight in milk, squared, just to show you he can. A cat's desire to scratch furniture is directly proportional to the cost of the furniture. A cat immersed in milk will displace her own volume, minus the amount of milk consumed. A cat's interest level will vary in inverse proportion to the amount of effort a human expends in trying to interest him.
Any pill given to a cat has the potential energy to reach escape velocity.
