CO：放通风处。我觉得吃的猫粮也重要。吃好的猫粮（成分前列是肉不是乱七八糟的）会有一些改善。

check the ingredients of your kitty food. if you see corn, wheat, flour, etc., the food quality is very low. The kitty will have to eat a lot to get the required nutrion. And the wheat, corn, flour, which she doesn't need, will make her poop a lot, with bad smell. Such food will also eventually compromise her immune system. Better quality food (made of muscle meat) will definitely improve the situation.
