Sorry I assumed Micro Chipping of cats and doge would be a Universal procedure , in Australia before you can register a cat or dog with the Local Authorities (Council) you must take the animal to a Micro chipping facility Vet or the local pound where they insert a small micro chip under the skin at the back of the neck of the pet , this procedure is supposed to be painless but my little fellow let out a fair howl when it was done 'this chip contains an individual code that can be read on a scanner allowing the reader to contact the owner if the dog is found alive or sadly dead ,the chip lasts the life of the animal and after the initial reaction Tango has never shown any discomfort ,in our Shire( Wyong) the dog registration is a one off fee for life of the dog or cat , the system is Australia wide so if he is lost interstate we hopefully get him back,
