Mine is microchipped and tagged with her name, my name and my phone number. She wears her microchip tag as well, so that if she were lost and were brought to a shelter or animal hosptial it would make the process of getting her back to me that much quicker. Some shelters do not have updated microchip scanners, the one i worked at still was using this older one that only found microchips from a certain company- i did not know this, we finally have one that also finds HomeAgain chips as well as others (I have HomeAgain for Zelda)- anyways just a scary thought and is why i like her to wear her microchip tag as well so they have her number instantly and know she is microchipped.
