I feed almost exclusively Fancy Feast, Sheba, & Science Diet. I don't like some of ingredients in SD or the high carbs but he only gets it on rotation. He LOVES Fancy Feast and the portions of Sheba are so handy. I have tried probably every brand of canned food in Pet Smart and higher end pet stores and he will pretty much always throw up and get diarrhea. He has gotten the 4Health occasionally but I am unsure if it agrees with him completely or not. After about a year or so I finally narrowed it down to the foods he can handle. He does get a very small snack of Hill's T/D in the evening. I would love to feed him a higher end food, I am very picky with the food my pets eat and don't mind paying for good food, but so far I have yet to find a brand that seems to agree with him AND that he likes. I am hoping to eventually try some raw with him, we just have a few vacations coming up this summer and I want to be home until I am sure he does well on it. (also, I will only feed the FF Classics, and I will once in awhile buy a fish flavor of the Sheba portions but probably not any more than once or twice a month)
