I've read a little bit about this topic. One thing a vet can do to help give your animal some additional protection out there is to implant a tiny RFID chip under it's skin. Theoretically, if kitty gets out and wanders away, a vet or shelter worker could pass a magnetic wand over it and get an owner's contact information. I was wondering if anyone had any practical experience with this? Has anyone heard a good reason -not- to do this?
