RE litter boxes in schools, I did read somewhere where there are a few teachers who keep a bag of litter and a cat box in their classroom closets just incase it's needed during a lockdown and some lower grade students need to use the restroom.
Makes more sense than the rumors and a lot of that information gets misconstrued along the way

The Jefferson County school district disputed Ganahl’s claims and said its dress code prohibits costumes at school. The district — where Columbine High School is located — has been stocking classrooms with small amounts of cat litter since 2017, but as part of “go buckets” that contain emergency supplies in case students are locked in a classroom during a shooting. The buckets also contain candy for diabetic students, a map of the school, flashlights, wet wipes and first aid items.
