Method calls in Perl are what is called "virtual" in other languages. If an object is blessed to Dog, and you call $obj->speak(), Perl searches @INC starting from Dog's.

Your constructor is already subclassable -- that's what your blessing to $class achieves -- so instead of calling Animal->new call Dog->new and Cat->new directly, and don't bother with the type; it'll happen automagically.

(You can tell what kind of Animal you have by calling ref $obj on an instance.)
