Interesting that those are the ingredients of the Mazuri tortoise pellets. I hear tortoise people raving about them all the time. I prefer to feed my herd of torts fresh fruits and veggies since it makes so much sense to know exactly what nutritional value they're getting and I know it's fresh, so I hadn't looked into it much. That doesn't seem like an ingredient list I would be pushing as being so good for nutrition and growth for my torts...I'm surprised they get so much praise.
