Recommended Desert Tortoise Diet

Desert tortoises are vegetarians. They thrive on a varied plant diet that is high in fiber and calcium, low in phosphorus, and pesticide-free. Avoid plants high in oxalic or phytic acid. Focus on grasses, edible weeds, flowers and spineless cacti. Do not feed any animal protein to tortoises. Don’t forget, tortoises also need plenty of sunlight and fresh water.
