It's a good food. My cat was on Natural Balance dry for about 2 years until I switched her to primarily Natural Balance wet food (the grain free flavors).
I was feeding the dry and canned of that. Charlie got UTI (probably not food related) and has to have RC for Urinary. But I still buy the canned Natural Balance and they love it. No other problems with UTI.
I'd like to go back to the dry, but don't want to risk Charlie getting another UTI.
