The Zoo Director Is Not An Animal
The animals in the zoo must be taken care of,
but the Zoo Director who does it is not an animal.
He's studied the ideal diet of every species,
but he doesn't dine on hay or raw, red meat.
The animals roar or pace all day in their cages.
He too stays at the zoo, in his office,
but he has the run of the compound,
and at night goes home.
