Allan Kardec. The book of spirits (№ 396913)

Question: the Soul of an animal, emerging from the body, whether it is after death, as the soul of man, in the wandering state?
Answer: It is a kind of wandering, since the soul here is not connected with the body, but it is not a wandering spirit. Wandering spirit is a being thinking and coming into harmony with his own free will. The spirit of the animal does not possess this ability. Identity is the main property of the spirit. A spirit animal is classed after its death spirits, which it is, and almost immediately used for further incarnations; he has no time to engage in a relationship with other spiritual beings.
