Part $3$: Feline and Canine

Feline and Canine are abstract classes that extend Animal. This lets us classify some animals more specifically, and reduce some code duplication. For instance, most of the canine and feline animals will use the same print statement for roam. Therefore, it is useful to write that in a superclass that all of the canines$/$felines can extend it instead of rewriting the method. We always want to reduce code duplication as much as possible. Both constructors should simply pass the name through to the Animal constructor.
