Furry PI's verdict

Open Farm Rustic Blend holds up well under the magnifying glass. Ocean herring leads the ingredient list — the right start for an obligate carnivore. It isn't flawless — pumpkin and spinach sit high on the list without being animal protein. Even so, the overall picture is good for everyday feeding.

What's concerning

  • Among its leading ingredients, pumpkin and spinach aren't counted as animal protein, and the top of the list is where cats need meat most — the main thing that kept it from a higher grade.

What works

  • Ocean herring leads the ingredient list — the right start for an obligate carnivore.
  • As a wet food, it delivers the moisture cats rarely drink on their own.
  • Carbohydrate load stays close to what a cat would eat in nature.
