What to Feed Your Sulcata Tortoise

Basic Diet

Sulcatas need a high-fiber, low-protein, calcium-rich diet. Along with fresh water, the most important staple in your sulcata's diet is grass. They are grazers, much like a cow, and love to walk all day lazily munching on it. Try to feed them at least 80% grass and 20% flowering plants, succulents, and weeds.

In summer months, you can easily go out into your own yard (untreated with chemicals) with scissors and a bucket and simply cut your own grass! Most types of grass that grow in yards are fine.

In winter months in places where grass stops growing, you can replace your sulcata's grass with timothy or orchard hay. Most pet stores and large department stores like Wal-Mart will carry these hays, although the cheapest route is buying in bulk at a farm supply store. You can also shop online and have them delivered.

Another good grass option in wintertime is Mazuri Tortoise Diet, a dried grass pellet type food that sulcatas love. You can simply put these pellets in a dish and spray them lightly to soften them up for younger sulcatas if you wish.

In addition to grasses, it is important that calcium be supplied to ensure good bone and shell growth. In the wild, sulcatas will eat plants found growing in calcium rich soil, thereby getting the calcium from that. Often they'll eat bits of soil that contains calcium while eating plant roots. They also seek out and eat bleached bones and desert dwelling snail shells to supplement themselves.

As our pets, they only have what we give them. You can give them a powdered supplement but it's easy to overdose them. The safest bet is giving them access to cuttlefish bones as they will eat them as they need it.

Toxic Foods

There are far more plants and weeds that are toxic to your tortoise. To see a complete list, please visit The Tortoise Table.

Never feed your sulcata most fruits or vegetables as they have too much water, vitamins and/or sugars for the sulcata to digest properly! Pumpkin is okay as a special treat along with yellow zucchini, grape leaves and watermelon rinds.

Absolutely DO NOT feed your sulcata dog or cat food (yes this happens). While wild sulcatas may occasionally eat carrion, they are herbivores and only need vegetation to thrive. Their bodies cannot break down proteins.

Feeding your sulcata the right foods is imperative to their good health and long life. The results of poor diets can be seen in the photos below.

When to Feed and How Much

Feeding a sulcata is pretty simple! You let him/her graze in their yard all day and supply them with their additional foods (listed above) a few times a week. They should grow slow and steady, too much or too little can cause pyramiding. If your tortoise is still indoors, feed them a pile of the approved foods as big as they are daily.

ALWAYS make sure your sulcata has access to fresh water (not including daily soakings). There is a myth that, because they're a desert species, they don't require water and this is simply not true and can cause illness in your pet.
