"Thankfully, it does," Alex said, unlocking the door to his office. Crow charged ahead of him, dragging his shiny prize to his favorite corner and curling up over it. Alex opened up the mini-fridge by his desk, pulled out a thawed dead rat, and tossed it over to Crow, who caught it in midair.
"Okay," he said, pouring some hand sanitizer from his desk into his hands and rubbing vigorously. "Follow me."
He locked the office behind them, continuing the talk as they walked past the more mundane reptiles and amphibians. "Anyway, the City moves things around so we have as much space as we need, but you still don't want to overcrowd things. And we get fresh meat for the carnivores, plants for the herbivores beyond what's provided in their habitats--we don't want them to over-graze--and even shipments of insects for the insectivores from who knows where."
They turned the corner and found the first of the dinosaurs, the habitat for small pteradons. They flitted and screeched, their small bodies brightly colored like leathery parrots.
