My cat threw up after food change and is now quiet. What's wrong?

You can try keeping him on a sensitive stomach food such as Iams limited ingredient, Fromm, or Purina sensitive stomach. However, it sounds like Keeko may have a inflammatory bowel disease and really the prescription diets have more reliable results. Also I would keep in mind that sudden switches from one food to the next can cause upset stomach issues in and of themselves. It is recommend to do a slow transition over the course of 7-10 days whenever you are making a food change. Website link on inflammatory bowel disease https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951476 You should at the very least get her examined and open up the conversation with the vet to do baseline bloodowork to rule out anything major and then ask for a prescription diet for Royal Canin Rabbit and Potato or Roylal Canin hydrolyzed protein diet, or HIll's Z/D Ultra to start her on a food trial. This is just 1 test to run so this should be something you could feasible do to at least get him started on something more reliable and effective. If the vomiting does not improve within a few weeks of being on the food, or if he develops any more symptoms, then he should be worked up further (i.e. abdominal x-rays). I hope that your pet Keeko feels better soon and stops vomiting so frequently. Best wishes and take care!

Vague behavior changes like you are describing can be the first sign of illness in an older cat, so if you feel something is wrong I would encourage you to see your veterinarian again. Blood work might be recommended to rule out kidney or liver disease. The vomiting could be a sign of inflammatory bowel disease or even an intestinal mass and if the blood work is normal an abdominal ultrasound might be recommended. Finally, the vocalizing and hissing could be a sign of pain from something like arthritis and there are some supplements and now pain medications that can be used in cats.

There can be many causes for the sudden change in activity level, including unhappiness with the new food flavor, pain from arthritis or another source of pain, GI upset from food allergy or dietary intolerance, anemia, constipation, infection, among many others. I would keep a close eye on his food and water intake, and monitor his bowel movements and urinations. If he is not back to himself in 48 hours, or if additional symptoms develop, he should see a vet for and exam and appropriate diagnostics.

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!

The possible causes of for vomiting are numerous. The fact that you recently moved (be in a month ago at this point) could play a role potentially as stress is a definite cause of GI upset in cats. Other causes can be dietary, gastroenteritis, pancreatitis, kidney / liver disease, allergies, foreign objects, and even cancer in some rarer cases in a young cat. Since there have only been episodes of vomiting total at this point, I wouldn't be particularly concerned as of yet. If you see this happening another couple of times over the next week, I think it is something worth investigating more. Hope this helps!

I can certainly understand being worried about Winston! Changing his food frequently can cause GI upset, and that may be a cause of his vomiting. You are correct it can be many things, and it is always good to have him examined by a vet. Hopefully the vet tomorrow can give you some answers and put your mind at ease :-)

It's very likely to be the switch up of food. withhold food for 8 hours then offer him boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his old food. If he continues vomiting or is not eating, take him to the vet to get treatment.
