Animals and Humans
600. Since an animal’s soul survives its body after death, is it errant like that of a human?
“It remains in a type of errant state, because it is not tied to a body, but it is not exactly an errant spirit. Errant spirits think and act of their own free will, while the souls of animals do not have the same ability. Self-awareness is the main attribute of the spirit. An animal’s soul is classified after death by the spirits responsible for that task, and it is almost immediately utilized. It does not have the freedom to connect with other creatures.”
