Why is my cat vomiting daily and not eating after food change?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 7 years old | 11.4 lbs

My cat vomits once everyday and barely eats. I have already changed his food and started giving him probiotic & prebiotic formula. But he continues to vomit semi digested food. What could be wrong with him?

Hello, I am sorry to hear about Romeo. Vomiting in cats can be caused by many different underlying conditions. Some cats do experience dietary allergies, so changing his food was a good idea. If this has not led to any improvement I would recommend having Romeo evaluated by a veterinarian. Other causes of vomiting can include systemic problems such as kidney/liver disease or problems within the GI tract (including pancreatitis, inflammatory bowel disease, etc). Your veterinarian can perform diagnostics such as bloodwork, abdominal x-rays, or possibly an abdominal ultrasound. This will help rule out some of the other potential conditions that I mentioned above. Hope this helps, good luck!
