Сократите. Как в пересказе.
One night Wild Dog felt a sweet smell which came from the Man's cave and he said, ' I will go and look what there is in the cave. And he asked wild cat, ' will you come with me? ' . But wild cat answered, 'I am a cat who walks by himself. I won't come with you'. Wild dog went to the cave alone and asked the Woman, ' Will you give me the bone that smells so good?' The woman asked, 'will you stay in the cave and help the Man to hunt?', and she added, 'Then I will give you sweet bones every day'. And wild dog stayed.
In the morning the Man saw Wild Dog and asked the woman, ' why is Wild dog here?' And she answered, ' he is not wild dog now, he is the first Friend. He will help you to hunt, and will get sweet bones for it every day'.
the next night wild horse and wild cow said, ' we will go and look where wild dog is. Will you come with us, wild cat?' But Wild Cat said, ' I am the cat who walks by himself. I won't come'. So wild horse and wild cow went up to the cave and asked the Woman, ' will you give us the grass that smells so nice?' And the Woman asked wild horse, ' will you stay in the cave and help the man to work?' And she asked wild cow, ' will you stay and give us your milk?' Then she added, ' I will give you this sweet grass every day'. And they stayed.
At last, one night, wild cat walked slowly to the cave, and the smell of sweet milk reached his nose, and he asked the Woman, ' will you give me this sweet milk?' The woman asked, 'will you stay in the cave and catch mice here ?' And she added, ' I will give you sweet milk every day'. But wild cat answered, ' I am the cat who walks by himself. I will not stay in the cave. But I will come when I want, and I will catch mice when I want, and you will give me this sweet milk when I want'.
