Saw this on Reddit today:

“Cats don’t go missing. You cannot “lose” a cat. Cats exist in a separate space-time continuum that occasionally contacts the one we live in (usually around your feet when you’re carrying groceries, or on your face when you’re trying to sleep.)Your cat is probably off bugging some dude in ancient Egypt to feed it, or coughing up a hairball in a V’lorgh space battle cruiser’s plasma converter flux intake. It will be back. And on the off chance that it doesn’t return, remember that it may be just that particular physical manifestation of your cat that’s gone, another avatar of said cat will show up when it’s hungry.”
