Cats sleep.
Many theories have been forwarded to explain this fact. They’re all wrong.
They’re not really sleeping. Cats don’t actually sleep very much at all. When they appear to us to be sleeping, they are in fact astrally projecting.
Their spirits are walking on the other side of the silver curtain, patrolling, hunting, protecting. Our weak human souls cannot survive the things that live on the other side of the curtain. Things constantly probing the barrier, seeking ways through, hungry for the very weakness that makes us vulnerable to their predations.
But cats. Cats are not so weak.
They have a strength foreign to our species. And better, they prey upon the very strengths of the creatures that would prey upon our own weaknesses. So.
Don’t waken your sleeping housecat. If you see a scruffy moggie stretched out on a sunny park bench, resist the urge to stroke its back. Let those cats be.
For if you interrupt their vigil, you might not make it home. You might simply disappear to the other side of the silver curtain, pulled beyond all knowledge of the universe, never to return to your own world. Or worse, you might not awaken come the morning to find yourself as yourself. Rather, you might rise a host to a parasitic alien entity, riding your body in search of new sources of sustenance in a hostile environment.
Neither is an attractive option. Far better to let the cat come to you, when it is ready. Once its vigil is fulfilled for a time. Then you may thank a cat for its attention, its persistence, its steadfast and honorable service.
