Friedrich cited the following examples to illustrate his contention:
A manufacturing error last year in the production of Royal Canin pet food resulted in excessive amounts of vitamin D3 in the food. This caused hypercalcemia, an abnormally high level of calcium in the blood that caused animals' kidneys to malfunction;
Research in endocrinology at Cleveland Clinic has confirmed that high levels of vitamin D3 in animals' blood causes kidney malfunction;
Symptoms associated with excessive vitamin D3 appear identical to the symptoms now being reported in dogs and cats. This has led "us to believe that this vitamin may be implicated in this new horror," Friedrich writes.
