I've heard of this thing called Tile. You place it on something you don't want to loose and you can track it via a phone app. Anyone ever heard of using it on a tortoise?
Yep, I used the tile on my tortoise while I was renting a vacation home and needed the extra emergency help...
You can find the link if you search "Bluetooth tracking device" or maybe someone using TFO on their pc will paste the link here for you. ? That way you can follow the journey and see how I used it without me re typing everything
