From my understanding there was some news story about a school in Colorado that had litter box and a bucket in a closet so the kids could go to the bathroom if they were barricaded in the classroom during a school shooting. Some conservative took that snippet of audio and turned it into this bizarre hoax about teachers showing up to class dressed as animals and shitting in litter boxes in the classroom. None of it made any sense and of course it never happened, but these idiots believed it because they're that f**king gullible.
