Ruby: Wrong number of Arguments for a subclass changes number of arguments

I am very new to Ruby and I have been looking for an answer to my question, but haven't found an answer yet. This is my code:

class Animal
  def initialize(aName, anAge)
    @name = aName
    @age = anAge
  end
end

class Cat < Animal
  def initialize(aName, anAge, aBreed)
    @breed = aBreed
    super(aName, anAge, aBreed)
  end
end

When I try to create a new cat object with defining three parameters, it says: ArgumentError: Wrong number of Arguments (3 for 2). But when I do the same thing with two parameters I get (2 for 3).

I can't seem to figure it out... Thanks for your help!

Your super class Animal constructor takes only two parameters aName and anAge. so you should only pass first two arguments of Cat to Animal.

class Cat < Animal
  def initialize(aName, anAge, aBreed)
    @breed = aBreed
    super(aName, anAge)
  end
end
