How to nest an Enum inside the value of an Enum

Question

I\'d like to know if it is possible in Java to nest Enums.

Here what i\'d like to be able to do :

Wouldn't you be better doing this with inheritance? Cat and Dog would be subclasses of Species. Persion would be a subclass of Cat and Pitbull would be a subclass of Dog.

What are trying to achieve by wanting to use Enums?
