Great for leopards, sulcata, Indian Stars and Pancakes
From the Tortoise Trust:
For large savannah species, such as Geochelone sulcata (African spurred tortoise) or Geochelone pardalis (Leopard tortoise), grasses and hays are a critical dietary component. Aldabra and Galapagos tortoises also do extremely well on this type of diet. Some other species also benefit from the inclusion of both fresh and dried grasses in their diet.
For species adapted to it, however, grass is not only nutritious, but its fiber content makes a significant contribution to digestive health. For leopard and African spurred tortoises, mixed grasses should comprise approximately 70-75% of the total diet
