Feline triaditis is actually three conditions occurring simultaneously: pancreatitis (inflammation of the pancreas), cholongiohepatitis (inflammation of the liver), and inflammatory bowel disease or IBD (inflammation of the intestines).
There may be no known “cure” for triaditis, though I would argue that proper nutrition is the absolute BEST method of treatment and prevention. By proper nutrition, I mean a raw diet or a canned diet – and most definitely no dry food/kibble of any kind.
