If you suspect that your cat may be from another planet, ask yourself these questions:
Do you sometimes wake in the night to find your cat fighting with extraterrestrial beings from another dimension that no one but the cat can see?
Does your cat often simulate life in an anti-gravity environment by rolling on his back to look at you upside down, or stretch into peculiar ballet positions in your arms?
Does your cat pretzel into strange sleeping postures that suggest she has undergone extensive astronaut training?
Does your cat try to communicate with extraterrestrials by meowing at the TV, sitting on short-wave radios, lying on the computer monitor, or in any way attempting to serve as an antenna for a piece of consumer electronics?
Does your cat stare at walls for hours as if receiving radio messages from the mothership through the plasterboard?
Does your cat respond to the phrase "Beam me up!"? Does your cat respond to anything in Klingon?
Does your cat meticulously push the sand around in her litterbox so that it looks crater-pocked like the lunar surface?
Does your cat's style of communicating with your computer seem more advanced than your own? For instance, does the cat sit on the monitor and look at it upside-down, or lay on the keyboard until the computer won't stop beeping?
Does your cat seem more intelligent than you are sometimes – and superior to you as well?
Finally, you should not confuse cats from outer space with those who've been abducted by aliens.
While the two kinds of cats are similar in many ways, cats who've been abducted by aliens like to run through the house crazily at night, jumping over furniture and scooting behind potted plants, re-enacting their escape from green men in saucer-shaped ships.
