The Cat Trailer works with Bluetooth and a smartphone app to track down your lost cat when they get lost. One of the smallest tracking devices available at only 0.28 oz (8 grams).
The app also provides a low battery indicator. The battery lasts 6-12 months and uses a replaceable button battery.
Will locate your cat up to 100 meters (328 feet) away. This is NOT a GPS. The app will tell you the distance to your cat, but not the direction. You need to search using the distance indicator until you find your cat. Check out the video for demo.
