She is throwing up about once a week, right after she gobbles down her food what I see is undigersted food

No just her usual food, that I feed to both my cats

Sugar, and she is about 2

Veterinarian's Assistant: What is the cat's name?

Sugar

Hi! I'm CalCatDoc and I can help with your question.

Since you found her, have you taken her to your local vet for any vaccinations and/or deworming?

What do you feed her? Brand/flavors of dry food? Brand/flavors of canned food? Any treats or people food?

I'm sorry that your question wasn't answered in a timely manner. Cats vomiting as Sugar has been doing are most often diagnosed with inflammatory bowel disease (IBD) - an idiopathic (unknown cause) inflammation of the gastrointestinal tract which usually responds to a glucocorticoid (steroid) such as prednisolone, the antiinflammatory antibiotic metronidazole, or both. We also need to consider a particularly nasty type of hairball called a trichobezoar, chronic pancreatitis or hepatitis, as well as a food intolerance. Sugar's vet will want to thoroughly examine her including performing diagnostics in the form of blood and urine tests. If nothing untoward is found, an abdominal ultrasound is indicated because that imaging modality is particularly sensitive for evaluating the gastrointestinal tract itself. We're mainly interested in seeing if the inflammation associated with IBD or its sequela small cell lymphoma (older cats, usually) is present.

Food intolerance/allergy is addressed with prescription hypoallergenic diets. These special foods contain just one novel (rabbit, duck, e.g.) animal protein or proteins that have been chemically altered (hydrolyzed) to the point that Sugar's immune system doesn't "see" anything to be allergic to. The over the counter hypoallergenic foods too often contain proteins not listed on the label - soy is a common one - and these proteins would confound our evaluation of the efficacy of the hypoallergenic diet. The prescription foods are available from her vet. There are many novel protein foods and a prototypical hydrolyzed protein food is Hill’s Prescription Diet z/d ultra (a hydrolyzed protein diet is my preference because it avoids the possibility of my patient being intolerant to even a novel protein). A positive response is usually seen within a few weeks if we’ve eliminated the offending food allergen. Food intolerance can arise at any age and even after my patient has been eating the same food for quite some time. Please respond with further questions or concerns if you wish.
