    He was the only gray cub(狼崽) of the she-wolf. The other cubs had red in their hair. He was gray like his father. He was the strongest cub. He showed more anger than his brothers and sisters.

He made more noises.

He was a carnivorous animal. He came of a breed of meat-killers and meat-eaters. His father and mother lived wholly upon meat. In his first months of life, he lived on mother’s milk, which was transformed directly from meat. And now, at a month old, when his eyes had been open for but a week, he was beginning himself to eat meat. 

There came a time when there was no meat. For many days the cubs did not eat. They were too weak and tired to play. One-Eye, the cub’s father, was killed in the fight over food. Even the she-wolf left the cave to find meat, but there was nothing. One by one, the cubs died. Only the she-wolf and the gray cub were left.

One day the gray cub ran out of the cave to hunt for his own food. He met a weasel（黄鼠狼）of his size. The rat-like animal ran at him and bit his throat. He was nearly dead when the she-wolf arrived just in time to kill and eat it.

The gray cub was not good at hunting yet, and still needed food from his mother. One day, the she-wolf brought him a lynx（猞猁）kitten. While eating, he heard great noise. The kitten’s mother had followed the she-wolf here. The she-wolf and the she-lynx started to fight, and they would fight to the death.          The bite was enough to give the she-wolf the chance she needed. The lynx was dead, but the she-wolf was badly hurt. For a week, she did not move. The gray cub had to find food for both of them.

Without his mother to take care of him, he learnt what life was about. Without meat there was no life. Animals had to eat other animals to survive. The law was: EAT OR BE EATEN.
