public string WhatAmI

get
{
return _WhatAmI

now that is setting _WhatAmI to. So now we have two areas in the coding that sets _WhatAmI, correct? No wait.. that is RETURNING the value of _WhatAmI to the string WhatAmI from the Interface... Let me know if I am wrong so far. So we are setting the private strings value in the method Animal(). Then we are creating public strings so it implements the Interface class. Then in those public strings we are setting the values in the Interface class. That Is why public string WhatAmI(get;) is in the interface. Because when you pass them to the Interface class it has to GET those strings you are passing.

So since we have Cat(string WhatAmI, string WhatIsMyName) ... which has to be there because you have to have it take 2 constructors the code : base("Cat", WhatIsMyNAme) is passing it directly from the method Cat() to the method Animal() since base is the class that Cat() derives from.

I hope I get got that right because if I did Im starting to get a much better understanding!! 

public string WhatAmI
{get
{
return _WhatAmI
}
