Create a classes Dog and Cat that extend Animal. Update talk,species and with relevant info.
Have a method in Cat and Dog - toHumanYears (which will print out how many years that animal is in human years [dog is 7yrs, cats is 4 yrs]).
Create a new subclass of Dog called PoundDog that will extend Dog.
Its constructor will initialize a dog but only have weight and visableAge (as a String
(they will put in - puppie, young, middle age, old) . The name will
automatically be set to "Unknown", the age is -1.
Override the talk command so that it calls the talk of the dog
class then, "please take me home, I dont want to be put down
Create a new method beg that will beg, that will return "give me more"
Override toString so that it returns - "This 12lb pound dog is
a puppie, and is of unknown age."
Override the eat so it will do the dogs eat then beg, then have it do dogs eat with 1/2 as much food.
