Furry PI's verdict

Our investigation turned up real problems with Against the Grain Tuna Mango. It contains tapioca. To be fair, tuna leads the ingredient list — the right start for an obligate carnivore. 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 tapioca, a lower-quality ingredient.

What works
