By Nature Grain Free · Chicken & Turkey Meal Recipe

Furry PI's verdict
Our investigation turned up real problems with By Nature Grain Free. It contains mineral oil. To be fair, chicken 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 mineral oil — an ingredient our database flags as genuinely problematic for cats.
- A high carbohydrate load for an obligate carnivore — a cat's natural prey is almost carb-free.
- A modest share of calories comes from protein.
What works
- Chicken leads the ingredient list — the right start for an obligate carnivore.
- Includes genuinely beneficial ingredients such as chicken and chicken fat.
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.
