Has anyone had experience with a cat that has been diagnosed with IBD? If so, what treatment and foods have been successful for you? After a round of flagyl, a daily (sometimes every other day during the "good days") dose of prednisone and Royal Canine Hypoallergenic food, my cat did great for almost 8 months. He's having a flare up and we started him on another dose of flagyl and it isn't working. Any suggestions would be greatly appreciated.
