ut radio tracking in pets  especially dogs and cats has become more common in certain social classes, however, experts now say that this type of device can cause cancer in pets. In the United States, many vets advise the use of microchips for animal identification (RFID) and most of the shelter requires. However, the safety of this device is very questionable, so that the owner of a cat has filed a lawsuit against Merck & Co., maker of chip HomeAgain, claiming that her pet’s cancer was a direct consequence of the implantation of RFID chips. Veterinarian Katherine Albrecht, an expert on side effects of the deployment of RFID, believe that this case is only the “tip of the iceberg “, as it has seen numerous cases of animals with cancer induced by microchips. Furthermore, she asserts that Merck and other big companies should seriously consider this process and move to warn their customers about the risk of using these devices as regard to the Natural News site. The site also notes that, according to the FDA (regulatory body for food and medications in the U.S.), side effects from this type of implant include “adverse tissue reactions.” Already the British Small Animal Veterinary Association says that the reactions include infection, abscesses and tumors. Now it’s the millions of owners of dogs and cats around the world to reconsider what is really interesting and for the sake of their pets. As David Gomez believes, writing for the website TG Daily, if something is not good for animals, is also not good for humans.
