Tips
- Protein is Medium (40% dry matter) on our label-based comparison range. Cats usually benefit from higher protein than dogs, so confirm the food is complete for cats and fits the cat's life stage.
- Fat is Medium (16% dry matter) on our label-based comparison range. This is a moderate energy-density signal for many cats, but total calories and body condition still matter.
