The assignment is to create a Python module called `hw3.py` that includes the definition of a `Cat` class with at least eight methods: `__init__`, `__eq__`, `__str__`, `__repr__`, `feed`, and three additional methods. The `Cat` class keeps track of the total number of cats owned, each cat's name, color, favorite food, and whether it is hungry or not. The module also includes a `main` function that allows users to interact with the `Cat` objects through user input.
