Your joking, right? Cartoon is not a mammal. It is a classification that has no direct relationship to mammal.
> ... then one concept is a subclas of the other
And that is the crux of the problem; in that it can lead to situations where a thing classified by the subclass, isn't necessarily classified by the respective class. For example, a robotic dog manufactured by Sony, is a dog, is a toy and is a machine, but it isn't necessarily a mammal (unless it actually has mammary glands which produce milk for its young, etc).
