I recently added a large leopard tortoise to my collection. I do not know what her diet was prior to my getting her. I have been feeding her a good variety of weeds, grass, leaves and cactus. She is still having issues with constipation. I recently started feeding her kale, romaine and more Mazuri with some "good stuff" mixed in. This seems to be helping. My question is are tortoises like dogs in that when you change their food, you should mix the foods for several feedings to prevent issues? I am going to have to switch the bulk of all of my guys diet to less good stuff in a month or so, due to winter, and am thinking how to plan for the change. I grow as much as I can inside,but not enough for 6. Thoughts and opinions welcome.
