难过的事情 The Sad Thing

I have raised a pet cat for two years, but since last week, the cat doesn’t feel like eating any food, it just lies down the ground and looks weaker. I am so worried about him, I want him to get better soon. So I buy him the delicious food, but it looks the same. I hope seeing the doctor can make him better.
