> The whole microchip registry thing is a mess, though. There's no authoritative database and I'm certain that the database entry for my cat is at some shelter where he was briefly held.

Yeah it is a mess, but my vet told me they use this to search across the dozens of registries in the United States: https://www.aaha.org/for-veterinary-professionals/microchip-...

That form is able to find my cat's microchip information in both the registries I have her on, for example. But yes, I was surprised the pet microchip scene isn't more consolidated. Like bicycle registrations are, where the two major U.S. players are https://bikeindex.org and https://project529.com

EDIT: But I was unable to read my cat's microchip with my Flipper Zero, even though my vet confirmed it's still readable using their more appropriate tool for the job.
