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!

    It sounds as Dolu is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

    I am so Sorry for your loss and that Dolu is now unwell as well. Unfortunately with clinical symptoms as serious as this, with one death already I have to advise you take Dolu to the veterinarian immediately. They will be able to start life saving tactics like IV fluids, and possibly even IV antibiotics which work rapidly. In the meantime you can keep Dolu’s fluids intake up with low sodium chicken broth. A bland diet of boiled chicken breast with no bones will help as well if he feels interested in eating. Thank you for using Petco Pet Education Center, formerly Petcoach and please post any further questions you may have. We are here to support you and Dolu.
