Yesterday they had an introduction to bugs—specifically worms, since I (strangely) could not find any rolly-polys in the back yard. In general the sharper of the Cheeples know that when the Tall Ones appear at the barrier, often times good things descend into their brooder. True, sometimes the Tall Ones themselves come in, and that's not so cool, but yeah, usually there's food. So they come running over to examine what we put in the litter.
"No, just watching. Seriously."
