Only problem with feeding a large dried diet and limiting the vitamin packed leafy greens is you can overload on food that isn't doing much more then filling up the stomach and not providing the necessary dietary items such as the proper amount of calcium, vitamins, and allow uro's to store fat. Overfeeding of dry foods MAY (I do not know for sure) lead to issues as the Uro ages, by not having the proper mix of necessities.
