Sims 4 Expansion Pack Ideas

I think a interactive zoo for a Pets expansion would be cool. The Pets world could be a giant zoo full of new creatures but still have community and houses in a nearby town. It would be cool if we had the ability to have a zookeeper job who would take care of the animals or the ability to own exotics. I'd also love more things for small animals, like being able to customize the animal and its habitat.
