The reasons why cats only vomit but not poop: 1. Foreign bodies in the gastrointestinal tract. Because the foreign bodies cannot be digested, they block the intestines and cause vomiting. 2. Trisomitis, including cholangitis, pancreatitis, and enteritis, can also cause vomiting in cats and secondary fatty liver. 3. The cat eats too little food and eats unclean food, causing physical discomfort.

What to do if a cat only vomits but does not poop:

1. Foreign bodies in the gastrointestinal tract. Because the foreign bodies cannot be digested, they block the intestines and cause vomiting. Since the cause of intestinal blockage cannot be determined by looking at it, it is recommended that the owner take the cat to the hospital for a X-ray examination to determine the cause of the blockage before treatment.

2. Trisomyitis, including cholangitis, pancreatitis, and enteritis, can also cause vomiting in cats and secondary fatty liver. It is recommended to promptly diagnose the cause and treat it with antiemetic drugs.

3. Cats eat too little food and eat unclean food, causing physical discomfort. It is recommended that cat owners check the cat’s recent diet and take some probiotics to regulate the gastrointestinal tract.
