Little bit off the topic, but just had a thought, if you study the Bible, there is evidence that all animals have a soul & spirit. The difference between man & animal is that man is created in the image of God. Before the fall of Adam & Eve which brought sin & thus death into the world, God had plans for man & animals to live in harmony. Remember, God is The God of Life, not death. Also, if salvation was meant just for people, it would say that in the Bible. Instead the Bible states that Jesus salvation is for all creation, all flesh, not just man.
Interesting.
