A class is a blueprint for an object. "Pet" is an object built say, from
the Dog class. You can't reference a Cat from a Dog. "Pet".name here is
"Fido" you reference Pet.Name, not Pet.Dog.Name!
Try thinking like this. A blueprint for YourHouse is used by a builder
to construct your house. If you want to go to the kitchen you go to
YourHouse.Kitchen not YourHouse.blueprint.Kitchen - if you try that you
will be standing on a piece of paper. Get the drift?

When the Pet object is the cat, the Main routine sets properties in the
Animal class e.g. Pet.Name="Tiddles". There is no need to access
Pet.animal.Name because Pet(Cat) _is_ an animal!
However, if you want to set an animal property inside a cat object then
it can be done by using the Me construct. Again read
