Create a Cat class with one int property: Age. Write a program that creates a List of Cat objects in a try block. Create multiple catch statements to handle an ArgumentOutOfRangeException, and an unknown exception, and a finally block to simulate deallocating the Cat objects. Write test code to throw an exception that you will catch and handle.

Modify Exercise 16-1 so that it does not throw an error. Create a custom error type CustomCatError that derives from System.Exception, and create a handler for it. Add a method to CatManager that checks the cat’s age, and throws an error of type CustomCatError if the age is less than or equal to 0, with an appropriate message.
