Today my cat had an ultrasound after a few bouts of vomiting and the Dr. Believes it's IBD. I've done some research on the disease but still have questions. He told me to restrict him to one type of food for the next 8 weeks or so to try and determine which protein may be causing the issue. If we determine that the protein I'm giving him is not the cause, can he then try other food with the same protein or will he be limited to one type of food for the rest of his life? The other question I have is more pressing; I have read that long term IBD can cause cancer-is this if the IBD goes untreated? Or it can happen anyway? Any advice anyone can offer on IBD will be greatly appreciated!
