OOPII - Inheritance - Quick Challenge - write a set of classes that represent a set of animals. There should be a Duck, Cat, and Dog instance that all implement an emote (**hint**: what sound does a duck make?) and a eat method. A constructor that takes a name as an argument should be defined elsewhere.

inheritance.rb

class Animal
  attr_reader :name

  def initialize(name)
    @name = name
  end

  def eat
    ["Stuff in nature"]
  end


end

class Cat < Animal
  def emote
    "Meow"
  end

  def eat
    ["Cat food"]
  end

end

class Dog < Animal
  def emote
    "Woof"
  end

  def eat
    ["Anything"]
  end
end

class Duck < Animal
  def emote
    "Quack"
  end

  def eat
    super + [ "Duck treats" ]
  end

end
