Every IBD kitty is different and what works for them is different. I know there are people who are huge believers in raw diets and for those with IBD kitties I am glad they found something that works. I personally don't believe that raw works for every IBD kitty.
I went through 6 years of vet hopping with a kitty that had undiagnosed IBD. He had the vomiting along with constipation and anorexia. He was also only 18 months old with his first flare and the vet though he had ingested a foreign object, understandable given his age and the symptoms. I never tried raw but I tried every conceivable commercial diet available and he would still flare There was no rhyme or reason to his flares. My kitty is on a small daily maintenance dose of prednisolone to keep his symptoms under control.
He does sound like he is having issues with stomach acid. I would ask your vet about giving your kitty pepcid to help control stomach acid. I take it you are feeding wet food which is good. Some people will leave out a small meal of frozen wet food. It takes a while for the food to defrost and come up to a temperature that kitty will eat it.
