So we all know that the human beings are created to serve as a energy source for the machines. And inside the matrix, the prison designed to keep us in line and oblivious to the fact we are batteries, there are people. To mimic the real world, I am assuming they put in animals, an example of which are the pigeons just before the Neo and Agent Smith fight in Reloaded. My question is: Are the machines breeding animals too? Or are they just a simulation of the animals that were most likely wiped out when we blocked out the sun? If the animals are connected to the matrix like the humans, how do they know how to create a residual image of themselves? Is this question answered in Revolutions? I'm waiting to buy the DVD.
