On top of gates and doors for staff members and for guests. I think there should be gates for animals that can be open and shut
The reason for this is that in real zoos, gates are used to shift animals around to different exhibits. This could work in Planet Zoo to keep solitary animals separate but you can easily unite them for mating
I also propose different gates for different sized animals such as
Big bois (Elephants, hippos, rhinos, wild cattle)
Giraffes
Big cats, bears, and great apes
Monkeys
Large lizards (Komodo) and crocodilians
Zebras and antelope (from gazelles to eland)
etc.
