Stop the food immediately and check whether the cat food is spoiled or inferior. Nowadays, more and more families are raising cats, which also gives unscrupulous businesses an opportunity. The new cat food that is determined to be replaced will cause diarrhea more and more. In severe cases, it is recommended to throw it away immediately. In addition, it is necessary to observe whether the cat is in good mental state and whether it is inactive or lacks energy. If there are no other symptoms but diarrhea, the owner should feed probiotics and antidiarrheal drugs to treat it. If other symptoms occur, send it to the doctor for examination.
