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 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. 
我养了一只宠物猫有两年了,但是自上周以来,这只猫不想吃任何食物,它只是躺地上,看起来虚弱。我很担心他,我希望他能早日康复。所以我给他买了美味的食物,但是它看起来一样。我希望看医生可以使他好得快点。
