My cat is throwing up brown and orange vomit weekly. Is it serious?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Female | unspayed | 11.02 lbs

My Tabi recently started to throw up more than usual. A few months ago she would throw up yellowish clear liquid but now she has been throwing up every week or so. This time she meowed really loudly, jumped off the couch and threw up on the floor. The color of the throw up is now brown with orange around it. I did change the food brand because I thought the previous food brand was making her sick. She's around 10 inches tall and weighs 11.02 pounds. I believe 3 years old.

Oh no! Lily is clearly having stomach issues. She may have food allergies, metabolic disease, inflammatory bowel disease, lymphoma, or any number of issues. Hopefully a simple prescription food allergy diet will help her. I recommend a vet visit for a full workup to include blood work, urinalysis, and abdominal radiographs. You could always try Hills z/d diet and feed ONLY that for 8 weeks to see if that helps first, but I would still recommend doing the workup so we aren't missing any serious health problems with Lily.
