Feline Inflammatory Bowel Disease


Inflammatory bowel disease (IBD) is a disease where inflammatory cells invade the lining of the digestive tract (stomach, intestines). The lining thickens and blocks food from passing from the body.

A cat with IBD will have periods of vomiting or diarrhea with weight loss and have periods of seemingly ordinary health.


In most cases, the cause is idiopathic (unknown). There are several possible causes, including:


Signs typically come and go, and they depend on which part of the digestive tract is inflamed.

In some cases, the entire tract is involved.

Other signs may include:


Your veterinarian will perform the following tests to rule out other conditions as the cause of the inflammation:

If all the above tests do not show any other conditions, your cat will need biopsies of the digestive tract to diagnose IBD.


There is no cure for IBD, but you can manage it by diet control and sometimes by medication:


The most effective way to prevent IBD is to feed your cat a diet that is high in fiber and low residue.


The prognosis is generally good once a good diet or medication is implemented. If there is no positive change to diet modification or drugs, the prognosis is more guarded.

Some cats remain on medication for life, while in other cases you may gradually be able to decrease the dosage.
