Many countries and regions around the world have adopted legislation that requires pet owners to have a microchip (foreign object) implanted in their animals.  However, there are serious problems associated with microchips and the scanning devices used to read these implantable devices.

Part of our goal is to stop mandatory microchipping legislation from being enacted and to reverse current legislation that requires animals to be microchipped. We encourage you to join our efforts.

Please note:  We are not responsible for information contained in other web-sites.  Because legislation changes, please check current legislation regarding mandatory animal microchipping.
