One day Mrs Healey found a stray cat 1 her front door, and because she was often alone she took it 2 her house. The cat was hungry, and she gave it something to eat. Now Mrs Healey was no longer alone, and she often sat in her chair with the cat, and they were both very happy. 3 some time, however, Mrs Healey noticed something strange. The cat was growing heavier and heavier. One morning, she found it in the spare room where she kept a lot of things. It was just putting a shirt and a warm scarf into an empty box. Why was it doing that, she wondered. The next day she knew the answer. The cat was proudly sitting in the box 4 four lovely little kittens 5 it.
