Animals have rights too

MAN is the only creature that consumes without producing. He does not give milk, he does not lay eggs, he is too weak to pull the plough, he cannot run fast enough to catch rabbits. Yet he is lord of all the animals – George Orwell, Animal Farm.

Of all the animals, man is the only one that is cruel. He is the only one that inflicts pain for the pleasure of doing it – Mark Twain, The Lowest Animal
