Oops, sorry.

I have been reading so much about it that I just started to use the acroynm. IBD is Inflammatory Bowel Disease.

Here is a brief description of it:

IBD is actually a group of gastrointestinal disorders, usually chronic in nature, which are characterized by an increase in the number of inflammatory cells found in the lining of the stomach or intestinal tract. These changes can affect the function of the organ involved. The causes of IBD are variable, and often no single cause can be identified in a given patient. The symptoms include chronic vomiting, diarrhea, or both, and in some cases, weight loss and change in appetite. Some patients may defecate outside their litter box, especially if diarrhea is present. The symptoms may be cyclical in nature, with the cat appearing to be normal at times. It is not unusual for these patients to be misdiagnosed as having hairballs.

I also found out that my vet is on the right track in trying to diagnose it. Here is something else I found:

A definitive diagnosis of IBD is only possible by intestinal biopsy, which is best accomplished using fibreoptic endoscopy. This technology allows veterinarians to diagnose and treat many gastrointestinal disorders more easily than in the past. The endoscope is an instrument that allows visualization of the stomach and intestinal tract through a flexible tube that is passed into either the patient's stomach or colon. The tube contains fibreoptic bundles that deliver bright light to its tip and transmit the images back into an eyepiece. Small, but adequate biopsies (about the size of this capital letter "O") can be taken using this instrument, thus avoiding surgery. The procedure is performed under a short general anesthesia with most patients able to return home the same day. Since endoscopic procedures are minimally invasive (there are no surgical wounds to heal) and short in duration, they are less traumatic to the patient and recovery time is quicker.

I know just a simple question, and see what I give you.
