So its a desert tortoise? I have 6 of them! lol, anytime you have a ? about them...fell free to pm me anytime! As for their diet, NOTHING STORE BOUGHT! It ruins there shells! You can give them weeds, grass, mulberry leaves, rose petals, and sprinkle a little bit of cuttlebone onto there food. Also, if its a desert tortoise you should bring it outdoors once in a while, dont keep it in a cage.
