After releasing ‘a fit bit for cows’ in 2018, Ceres Tag in collaboration with Data61 has been developing a prototype tracker for cats and dogs. The Companion Collar will be able to track an animal’s movements in real-time, sending updates to your phone whenever your pet wanders outside of a virtual boundary. It requires monthly charging that is dependent on the amount of wandering your four-legged friend does. 

Homebodies who remain within the virtual boundary will trigger the device’s automatic power-saving mode that only uses Bluetooth. But little adventurers who leave their boundary will switch it to GPS location and direct satellite reporting.
