Answer:
The setting of the story, an isolated island, makes it mandatory for the cat to save her own skin. Hunting for herself and working for her survival, she has to look for her own food, contrary to the life she used to live. As she had been a pampered house cat, she will have to learn and strive to keep herself alive.
Explanation:
The story "How a Cat Plays Robinson Crusoe" by Charles G. D. Roberts is about a pampered house cat stranded on an island and had to live on her own, away from the usual human protection and provisions. The setting of the story makes it mandatory for her to either learn how to survive or she can do nothing and die. As she had been taken care of always, she will find it hard and even impossible to learn to live by herself. But if she is to survive the ordeal, she will have to change herself. She will have to learn how to hunt, and provide for herself. When the hoards of rats arrived, she have to learn how to hunt and kill them, for she's basically a cat by nature. And the coming of the storm and the winter will help in her learning how to survive and take care of herself, without any help from her humans.
