Cat Irritable Bowel Syndrome and Pet Promise Cat Food Discontinuation

I have a Persian cat, Murphy, that has had irritable bowel syndrome (IBS) for several years. After the vet wanted to do exploratory surgery to find out what exactly was going on with Murphy, I decided to take matters into my own hands. I didn't think surgery was the best route. I started experimenting with different cat foods. I tried Science Diet prescription canned foods and some holistic duck canned food, but Murphy was still exhibiting the same symptoms: throwing up and loose, bloody stools.

I finally found Pet Promise cat food, which doesn't have byproducts, that Murphy was able to tolerate. Unfortunately, Pet Promise was discontinued in January 2010.

Since January, I have been experimenting with different cat foods to try to find one that Murphy can stomach, so to speak. I first tried Blue Spa Select, but Murphy's bloody stools returned. I now have Murphy on Iams ProActive Health MultiCat kibble, and so far so good. He's been on the food about a week. I'm crossing my fingers that this food will continue to settle well with Murphy. Cat IBS is such a difficult disease to effectively treat and manage.
