My two cats recently had microchips implanted. The vet, however, lost one of the cats information (entire envelope of information).
The vet scanned the microchip and wrote down the number associated (15 digits) on a card and said that's all we need.
My other cat came with sterility expiration + some extra number + stickers containing the barcode + various cards etc.
Am I missing any important information at this point, and if so, is there anything I can do about it?
