Hi everyone,
I wanted to share our experience of keeping an outdoor cat safe, as we made a massive mistake at the start by trying to avoid paying a monthly subscription.
We first fitted our cat with a Bluetooth tag (like an AirTag or Moto Tag). These tags don't have a standalone GPS module or a SIM card; they rely entirely on people with compatible smartphones and Bluetooth enabled passing nearby. When our cat went missing, the app only showed the last recorded position at our house. For 9 days, it was impossible to locate her, even though she was in the fields just 500 yards from home. The position only updated once she was taken to the vet by the people who found her.
They're fine for keys or a wallet in a city, but for a pet in suburban or rural areas, it gives a false sense of security. We’ve now switched to a proper cellular GPS tracker (Tractive).
We’ve documented the full story of the search and a technical comparison between Bluetooth and GPS with a SIM card here: https://petgps.eu/fr/#historia
