Answer:
2. Mother is worried the cat will get hurt going over the wall
Step-by-step explanation:
From the story, "Once Upon A Time", the mother is actually worried about the cat because she felt that the cat will get hurt going over the wall.
The cat is fond of climbing the wall. So when the razor-bladed coils where fixed around the wall of the house, the mother was worried about the cat getting hurt while trying to climb through the wall.
Below is an excerpt from the story that supports my answer:
"And she waited until the little boy had run off to play before she said, I hope the cat will take heed. . . . The husband said, Don’t worry, my dear, cats always look before they leap. And it was true that from that day on the cat slept in the little boy’s bed and kept to the garden, never risking a try at breaching security."
