Uhh, your door may have radiation in it.
a proposed long-term nuclear waste warning message that could be understood 10,000 years in the future
If I was some post-apocalypse caveman and I saw a glowing cat I’d assume it was a god and just live wherever it glows.
You missed the part about the atomic preisthood and “inventing a body of folklore, passed on through proverbs and myths, to explain that people should flee when a cat changes color.” Such as the cute little song
Don’t change color, kitty.
Keep your color, kitty.
Stay that pretty gray.
Don’t change color, kitty.
Keep your color, kitty.
Keep sickness away.that will not last 10,000 years
Well, people like you can die a horrific death while me and my non-glowing kitty will stay away from Mount No Place Of Honor. And she can have a little ham, as a treat for keeping me safe.
I’m not going to die I am going to be transformed into a radragon.
You haven’t heard it. It’s catchy
There are many more interesting proposed approaches though. Like creating a religious cult around avoiding nuclear waste, all kinds of hostile-looking architecture, and my favourite is the idea of stocking waste in containers so durable that any people advanced enough to break into it would have to be advanced enough to know how to behave around nuclear waste
what if the cat is orange tho
There’s more verses
My door turns purple when it’s about to eat a cat.
What am I, some sort of pupae expert!?
My black cat often licks the bottom of my bedroom door for reasons beyond my understanding
