Cat trackers look alike but locate your cat in two very different ways. A GPS unit reports its own position over satellite and mobile networks. A Bluetooth tag instead relies on other people's phones passing nearby and reporting where it was last seen. That single difference drives range, running cost and battery life alike.
A GPS tracker reports its live position wherever there is mobile coverage, which is what you need when a cat has actually got out. A Bluetooth tag only updates within radio range, or when someone else's phone happens to pass by. In quiet residential streets and outdoors, expect long gaps between updates.
GPS units need a data plan, and among the trackers listed here they run 2–15 days per charge. Bluetooth tags need no subscription and last on the order of a year to three years. The choice is really between low running cost and dependable tracking.
Cats are small, and anything hanging from the neck shows up in how they move. The trackers here span 4–36 g — a ninefold spread — with GPS units at the heavier end. For a small cat or a kitten, it is safer to shortlist by weight first and features second.
Think of it as insurance against the exception — an escape — rather than day-to-day tracking. If your cat stays inside, a subscription-free Bluetooth tag with a long battery is usually enough to find it indoors or nearby. If there is a real chance of it slipping out a door or balcony, GPS is the safer answer.
Correct — cat collars are built to release under load, and that is a safety feature, not a flaw. Check that your tracker attaches to a collar with that breakaway design. It also means planning for the case where the collar comes off and takes the tracker with it.
