You're just making things up, just like those people perpetuating the litter box hoax.

> The only known official instance of cat litter being placed in school classrooms for potential use by students was in the late 2010s by the Jefferson County Public School District in Colorado, where the 1999 Columbine High School massacre took place. Some teachers were given "go buckets" that contained cat litter to be used as a toilet in an emergency lockdown situation, such as during a school shooting.

_Only known official instance_ and not for drills, but in case there was an emergency situation.
