Assignment2 Zoo Management UML Diagram

Animals:

Horses (horse, zebra, donkey etc.),
Felines (tiger, lion etc.),
Rodents (rat, beaver etc.)
Most of the information stored about animals is the same for all groupings.
species name, weight, age, etc.
The system should also be able to take the dosage of specific drugs for each animal => getDosage ()
The system should be able to calculate the feeding times => getFeedSchedule ()
The logic for the system to perform these functions will be different for each grouping. For example, the feeding algorithm will be different for horses and different for tigers.

Using the polymorphism model, design a class diagram to handle the situation described above.
