Often misdiagnosed in cats as being hairballs, since vomiting and diarrhea are among the symptoms, IBD occurs most often in middle-aged and older animals. IBD is usually diagnosed after other diseases, such as diabetes, hyperthyroidism, kidney disease have been ruled out with the results of a complete blood panel. Definitive diagnosis of IBD can be achieved through mucosal biopsy of intestinal tissue usually through fibreoptic endoscopy. This procedure requires a short general anesthesia.

Once diagnosed the disease can be treated through dietary modifications, but most commonly through oral administration of prednisone, a form of cortisone.

In the case of Jasmine, my 12-year-old Himalayan, who was so debilitated from weight loss over a two-year period, my veterinarian ruled out the invasive tests and prescribed the medication on a trial basis. (Blood tests had previously ruled out the other diseases mentioned above.)

The results were truly amazing. Within days of starting the twice-daily dose of prednisone Jasmine had started eating willingly and both her frequent vomiting and diarrrhea ended. An added side-effect of the prednisone is increased appetite, which for a finicky cat has been an enormous benefit.

From being an emaciated cat weighing less than five pounds, Jasmine is now almost plump, and approaching seven pounds after only two and a half months.
