Dancing Cats Silent Canaries is a compelling story written by a traditional doctor to help parents frightened by the risks of their baby succumbing to sudden unexplained death or disabling neurological and respiratory diseases. It is about the failure of doctors, including the author, to pay closer attention to lurking dangers associated with environmental toxins and vaccines never conclusively proven safe. This book depicts critically important roles being played by manmade toxins in Crib deaths and the rapidly growing epidemic of neurological disorders, especially Autism. Largely ignored evidence will be presented that will give parents a better understanding of the problems and the solutions. Parents will learn that Crib death victims are modern day canaries caged in a crib silenced forever by well known nerve gases. They will also learn that children, who manifest behaviors described as autistic are similar to mercury poisoned cats which appear to dance. Reasonable and easily understandable steps to protect babies from conception through the critical first year of life will be offered. Evidence will be provided that Crib death is preventable and recovery from Autism is possible. The study proposed study may show Autism may also be preventable. . This author will reveal important research that shows there are inherent dangers in baby mattresses made from polyvinyl chloride (PVC); a well known toxic plastic. PVC will become far more dangerous if contaminated with common fungal organisms known as mildew. A PVC mattress infested with mildew is a time bomb. Mildew can generate gases more toxic than cyanide from elements found in this plastic. Parents worldwide, who have chosen to eliminate exposure to PVC and mildew, have not experienced a Crib death. The author, David Denton Davis MD, has been forced to also conclude some disease preventing immunizations are actually far more dangerous than anyone may have previously imagined due to adverse event under reporting. His painful admission that he failed to comply with the National Childhood Vaccine Injury Act (NCVIA) by not reporting illnesses occurring within 28 days of an immunization was followed by a query of his emergency colleagues. He was not surprised to find not a single physician had ever submitted a form to the Vaccine Adverse Event Reporting System (VAERS). It became apparent these reports are systemically being ignored in urgent care centers and emergency departments throughout the United States. Similar responses from Pediatricians led him to the conclusion only 1% of adverse vaccine events are likely being reported each year clearly indicating the passive safety net offered by VAERS has been a dismal failure. The evidence against PVC and the likely magnitude of unreported adverse vaccine events indicate these products can no longer be trusted. Therefore Dancing Cats, Silent Canaries asks for the invocation of the Precautionary Principle: a moral and ethical policy that offers a protective warning and requests a temporary ban. Without cause and effect evidence of a product%u2019s harm this new belief shifts the burden of proof for the safety of PVC and each vaccine to manufacturers. While parents await the outcome they will be advised to eliminate exposures. Dr. Davis has introduced a resolution to the American College of Emergency Physicians asking for reporting help from an estimated 25,000 member physicians staffing more than 6000 hospitals. Parents of children, who have received a vaccine within 30 days of an illness, must remind nurses and doctors of their legal responsibility to report.
