[Strapping a Raspberry Pi & Battery to an animal is not very friendly
Using a GPS Collar may be more comfortable for your Cat
Sorry thats what i meant to say, the only GPS modules i could find where add on boards to the pi itself. I dont think i could fashion a draggable device!!! Or if i could it wouldnt go far ......... But then i wouldn't need the tracker ........ (no wait thats cruel) back on point
Something that could be attached to a collar, then either downloaded when the cat returns or somehow pinged live, maybe by using a Sim card?
