Don’t go by what’s recommended on the bag as that is way too much. Their diet is made up of mainly hay - 80%. Veg makes up 15% and pellets the remaining 5%.
Pellets are the least essential but they provide the vitamins and nutrients that may be missing from their diet. They are also the largest contributor (along with unfiltered water) to calcium in their diet. Even more than high-calcium veg! They are also the chocolate of the piggy world. Hopefully that helps you understand why they are so limited.
@superka She likely isn’t misreading it. That sounds about standard for recommendations on packaging. 30g could be between 4-6 tablespoons, depending on the pellets.
