==Calcium Metabolism==

Rabbits have a unique calcium metabolism. Calcium is absorbed across the intestinal wall in the absence of vitamin D, which other mammals require for calcium absorption. Less regulated calcium absorption results in calcium being excreted in the urine. Parathyroid hormone and [[Calcium Homeostasis - Anatomy & Physiology|calcitonin]] regulate blood levels. Kidney stones and calcification of soft tissue may occur if a high calcium diet is fed to rabbits for a prolonged period of time.
