In order to diagnose acute vomiting in cats, all you need to do is take a sample of your cat’s vomit to the veterinarian.

If the veterinarian could not identify the issue properly, then he or she might ask you to limit the diet of your cat and then collect the sample of the cat’s stool over the period, as the cause might be passed in the stool. Cat’s body occasionally uses vomiting to clear the toxins in the intestines. 

If there is excessive mucus in the vomit, then the issues might be an inflamed intestine. If there is undigested food in the vomiting, then it could be due to overeating, food poisoning, or anxiety. On the other hand, bile in bile in vomit might indicate pancreatitis or inflammatory bowel disease.

In the case of intestinal obstruction, strong digestive disorders are usually observed. If the veterinarian suspects obstruction in the esophagus of your cat, then he or she might conduct an oral exam.
