I used to feed my cats various formulas from Science Diet(weight management, sensitive stomach, hairball formula, prescription) through the years but it caused to many problems. That is when I switched to Eagle Pack. Since my cats have been on Eagle Pack, a holistic brand, it really has done wonders. My oldest cat Panther used to suffer from IBD but once I switched him to Eagle Pack it completed disappeared. No more runs or vomitting.

I've heard that Dick Van Patten's Natural Balance Venison & Green Pea Formula for Cats is supposed to be really good too.
