The Cat That Walked Through Walls

For those of you who have read Robert Heinlein's "The Cat Who Walked Through Walls", that cat lives with us.

His name is Stinger. Purebred Siamese, about twelve pounds, chunky around the head and neck; he's full of testosterone and "don't mess with me" attitude. He patrols the neighborhood at all hours, keeping outside males away from "his girls", while at the same time exhibiting amazing tolerance towards all his sons who still live at home. In other words, he only hisses and cuffs them when they stick their noses in his food, not beat the crap out of them as he easily could.

He’s supposed to be an “outside cat”, but he appears, without any announcement, inside the house at random intervals, and immediately walks over to rub and purr against my leg.

I affectionately refer to him as "my dog", because he then rolls over, just like a dog, exposing his belly for me to scratch

Here's why this is a mystery: this has happened many times when I had just thrown him out, when no one else was at home but myself, and I had previously checked ALL the doors and windows inside our huge house to make sure they were closed. There is simply no other plausible explanation.

The fact that my cat can walk through walls proves to me beyond a shadow of a doubt that not only are all the possible universes connected, but that pieces and chunks of them may appear (according to some as-yet-undiscovered universal chunk theory) at certain times and places in yet other universes (and vice-versa).

Here's how it works: my cat can see when a piece of wall from another universe appears for a minute or two in the middle of a wall that exists in our universe, and then he simply walks right through that patch of wall into the house.

This is possible because the molecules that comprise the patch of wall from the other universe are vibrating at a different rate than the matter he's made from; it's effectively transparent to his solidity and doesn't provide any bar to his passing through. He sees it just like we see a door in a wall, but his "door" just looks like a homogeneous wall to us.

(loud applause!) Thank you, thank you. However, given my lack of higher education, this is probably destined to be my total contribution to the debate regarding the possible existence of alternate universes and realities.

And frankly, as far as David Deutsch is concerned, if he had ever brought back a single thing from any other universe than the one we have all more or less agreed we exist in, that would surely be a proof that the other stuff he's claiming could at least be possible.
