The wild animals can all be arranged on seven lines leading up to the domestic animals; for example, the fox and the wolf are obviously on the same line with the dog, while the lion, the tiger and the leopard equally obviously lead up to the domestic cat; so that the group-soul animating a hundred lions mentioned some time ago might at a later stage of its evolution have divided into, let us say, five group-souls each animating twenty cats.
The life-wave spends a long period of time in each kingdom; we are now only a little past the middle of such an aeon, and consequently the conditions are not favourable for the achievement of that individualization which normally comes only at the end of a period.

Rare instances of such attainment may occasionally be observed on the part of some animal much in advance of the average.

Close association with man is necessary to produce this result.

The animal if kindly treated develops devoted affection for his human friend, and also unfolds his intellectual powers in trying to understand that friend and to anticipate his wishes.

In addition to this, the emotions and the thoughts of the man act constantly upon those of the animal, and tend to raise him to a higher level both emotionally and intellectually.
