As soon as I saw the cat in our yard, I knew he was a stray (流浪儿). He looked 36 —a wounded warrior with a badly scarred body. I started putting out food for him each day, but he wouldn’t come near me if other people were 37 . Winter came, and he still wouldn’t 38 us. Then, one day, a car hit him so we took him to the vet’s. After a week, we were eager to bring him home to 39 our family. But when we went to take the cat home, the vet told us we should put him to 40 immediately because the cat was so fierce and mean that he would 41 become tame , let alone a pet. But I have always had 42 in love’s power to 43 even the wildest beasts. I told the vet, “I want to take him home.” We 44 him Paws. Three days went by, and we only knew Paws was 45 the bed because when we walked past it we heard deep growling. I wanted to somehow let him know he was 46 and loved. So I put on a hard hat and a pair of welding gloves. I 47 under the bed toward Paws, with my face to the 48 and only the top of my head facing him. I 49 out to stroke (抚摩) him gently over and over again. He growled and tried to 50 and bite me. It was scary—but I knew he couldn’t 51 me, so I just kept going. Slowly, he began to 52 . Then I slid out from under the bed and left the room. Several hours later, I noticed a cat on the bed. It was Paws—all 53 on the pillows! I couldn’t believe it. That dear cat became the 54 of our household. Although Paws finally died of cancer, his legacy(遗赠)—my 55 and firm belief in the power of love — lives on.
