Vitamin D-dependent rickets type II in a cat.
A cat with clinical signs Indicating rickets was diagnosed as having a defect of vitamin D receptors. Clinical signs had been seen from four months of age. Treatment with calcium supplementation and various forms of vitamin D did not alter plasma calcium levels or reverse skeletal lesions of lateral antebrachial bowing, lumbar spinal lordosis and costochondral beading. Analgesics were effective for relieving skeletal pain during the bone growth phase and were withdrawn when the animal reached skeletal maturity. Therapy for hip osteoarthritis was given from five years of age until the cat was euthanased at nine years of age as a result of refractory hip pain.
