there is a Factory making plastic Cats and Dogs. They make some cats and 
dogs
every day. Truck drivers arrive from time to time and get new products for
further processing. Plastic cats and dogs are not sorted by the factory, 
they
are mixed together and have the same price.

How the factory should be modeled?

struct Factory
{
    ?
};
