April has been dry hacking for a few years now, and has seen 3 vets with no answers. I summed it up to her having a sensitive stomach to "canned" food. She will barely touch dry food. Then Freshpet came along. YAY! She L-O-V-E-S IT! I combine a piece of the roll with the "kibbley" stuff Vital makes. Depending on where I am shopping and what's available, either the FreshPet Select or Vital she loves them all. The kitties come by to make sure she's cleaned her bowl. I sometimes will give them a little piece. And her dry hack has all but ceased... although I do hear her... very rarely than what it was.
