One of my cats recently went missing. He was gone over Winter for almost a month in the freezing cold. Thankfully, I was reunited with him. To avoid this happening again in the future, I wanted a device to track my pets. After lots of research, I decided on the Apple Airtag. While Apple has stated that the AirTag is not meant for tracking pets, it seems to be best product on the market, compared with bulky, expensive and unreliable GPS products. Cats don't seem to mind it either!
