Furry PI's verdict

Our investigation turned up real problems with Diamond Whitefish Dinner. It contains whitefish. To be fair, as a wet food, it delivers the moisture cats rarely drink on their own. On balance, most cats are better served by stronger options — the app can suggest better-graded foods of the same type.

What's concerning

  • Contains whitefish, a lower-quality ingredient.
  • Several other ingredients on the label raise quality questions — the full flagged list is in the app.

What works

  • 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.
  • Includes genuinely beneficial ingredients such as chicken and chicken liver.

The grade is only the cover of the case file. The free app shows the full 100-point breakdown, every flagged ingredient, and better-graded alternatives for your cat.
