Here at David's Jungle we feed Mazuri Tortoise Diet to all of of our tortoises a few times a week. We like our tortoises to eat a wide variety of foods. Mazuri is one of them. Mazuri Tortoise Diet contains a wide range of vitamins and minerals like calcium.
We like to soak ours in a little bit of water for a few minutes to soften it before feeding. It is not necessary to do when feeding the adults, but they do prefer to eat it soaked and softened.
