HI there. So sorry Onyx is having this issue. If those medications are not working I would be worried about the possibility of something else going at. She may not have IBS at all. My suggestion would be to get some intestinal biopsies so you can have a definitive diagnosis. Without a diagnosis all your vet is doing is guessing as to what may be wrong. If you want proper treatment you need a diagnosis first. Here is a link to an article about chronic diarrhea in cats: https://www.petplace.com/article/cats/pet-health/chronic-diarrhea-in-cats/ In the meantime you can add in a probiotic to the diet. I suggest Fortiflora, it is the best. No human probiotics and no dairy. http://www.allivet.com/p-1130-purina-pro-plan-veterinary-diets-fortiflora-dog-supplement-box-of-30.aspx Hope this helps. Best wishes.
