That's a pretty broad question. The answer that I will provide concerns a more Vedic perspective. Vedic astrology is great for questions about the soul. Tropical astrology is good for questions about the psyche, which is how the psychology chooses to express the soul. Animals, as you might surmise, do not have the same kind of souls as people as a general rule. Some, however, might get closer than others. Introspection makes people different than the animals, and indeed, meditation is a kind of introspection which confirms the suspicion.

homo sapiens, individuals, humans, persons are animals. 1 man = 1 man
