What is a GPS tracker for furry friends?

A GPS tracker for my cat, a funny idea? Not that much ! Bring your cat into the 21st century and equip it with GPS tracker for cats . Follow her movements at any time on your smartphone: so no more cold sweats when kitty does not come home at night or rounds in the neighborhood with a roll of tape in hand to put up posters.
