"cat" is actually an command used in the ancient UN-IX computer operating system, which was developed in Egypt by a courtier known as Rich-ee during the reign of Pharaoh Kentom-aten. "cat" is one of the most commonly used commands, and when executed at the command line gives the following result:
This hieroglyphic had a passing resemblance to Rich-ee's pet animal (which incidentally kept walking over her keyboard). Because of this Rich-ee named the animal "cat", which has stuck ever since.
The "cat" command had such an enormous impact on the fortunes of ancient Egypt that the animal became greatly reverenced as a symbol, and eventually deified into the Egyptian Pantheon of the Gods.
