FWIW, the last 2 links looked like they could be personalized so you could put on the tag whatever you wanted. I didn't care for the ones that had the texting or website things, either, and completely agree with you. I think one of those could also put the phone number on the tag so the person who found him could call you.
Is Vlad microchipped? If so, would the information on that have to be updated as well? I don't know much about micro-chipping as I never had Pookie chipped.
