My cat is vomiting, not eating. Could it be IBD? What are next steps?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 11 years and 9 months old | 9 lbs

My cat (11y/o spayed) began vomiting once a week about a month ago. I had assumed that it was a hairball problem, but last week I noticed that she hadn't been eating, and after I got her to eat, she vomited. I took her to a clinic. Blood panel, thyroid, and x-rays came back normal, and I have been feeding her as much A/D food as possible. Clinic said possibly IBD or GI Lymphoma. She is uninterested in food and has vomited every morning for the last 2 days. What should my next steps be?

I'm sorry to hear that Mercedes is sick. If IBD or GI lymphoma is suspected the next steps may be ultrasound or even biopsy. Biopsy is needed to confirm the diagnosis of IBD. However, I will frequently treat if it is strongly suspected on ultrasound.

If IBD is confirmed it's worth doing a trial of a prescription GI diet. Although a/d is a good recovery diet it is probably not the best one to use as a maintenance diet if IBD is suspected.

It would also be worth giving your veterinarian a call to see if they can give a Cerenia injection. This will help to resolve the vomiting and can be continued if necessary.

Vitamin B12 injections can also be helpful when a cat is experiencing GI distress and will be needed if IBD is confirmed.

Thank you for using Petco Pet Education Center, formerly Petcoach and best wishes to Mercedes!
