Itโs entirely possible to be pellet free, so do what you are happy with.
Pellets are the least important part of the diet In any event. They should only have one tablespoon per pig per day.
Pellets are useful as they fill in any gaps in nutrition and ensure they get all the vitamins they need. But, they are also full of fillers and things which piggies donโt necessary need.
the choice is yours! If your piggies are healthy and happy without them, then donโt add them!
