Although cats and dogs are carnivores, they not only eat meat, but the bones as well, which supply the needed calcium and help to create a better calcium and phosphorous balance. Because of the low intake of calcium, the parathyroid gland produces more parathyroid hormone, and calcium is removed from the bones. Kittens and puppies with secondary hyperparathyroidism are often reluctant to move, may stand splay-legged, and may easily develop fractures because of the thinning of the bones. The changes in the density of the bones often cause abnormal growth, especially in the spinal column and pelvis. This places stress on the joints and can result in arthritis.
Treatment basically involves placing the animal on a balanced diet.
