A 25 g mounted weight, true Cat 1 GPS, five-second tracking, bundled service, and product-level reviews are strong; a 4 kg floor and inconsistent battery copy reduce confidence.

Petloc8 Mini GPS Tracker is worth considering if best bundled-service value for pets above 4 kg is your priority in true cellular tracking under 34 grams. Check fit, current price, and retailer availability before buying.
Skip it if above-4 kg recommendation excludes many toy dogs and small cats is a dealbreaker, or if your pet needs a different fit, size range, or retailer return policy.

FitBark
FitBark GPS 2nd Gen matches Fi Mini at 16 g and supports on-board GPS, multi-network LTE-M, Wi-Fi, cell-tower assistance, and Bluetooth. It works for pets from 5 lb in four officially supported countries and has flexible long-term subscription pricing, but the battery claims vary dramatically by mode: the six-month figure is Bluetooth-only, while continuous live GPS is rated up to six hours.
PAJ GPS
PAJ's PET Finder 4G Mini is a true GPS tracker with its own European 4G SIM, Bluetooth-assisted indoor power saving, a 33.1 g body, and a 3 kg minimum dog weight. Its purchase includes more than two years of service and the official page provides unusually complete technical and media evidence, but it is the heaviest tracker in this lightweight ranking, continuous tracking lasts only one to two days, and it is not designed for U.S. cellular use.
Fi
Fi Mini weighs only 16 g and is explicitly positioned for puppies, small dogs, and cats, with real-time GPS, Verizon LTE-M, IP68 protection, and flexible collar or harness attachments. Its latest comparison page advertises up to six weeks, or up to three months with a Fi Base, but those are conditional maximums; service is membership-based and the public brand review profile is unusually polarized.
Molly&Cody
Tracker T1 is a roughly 25 g pet tracker that officially lists GPS, Wi-Fi, LBS, Bluetooth, and—on its technical page—cellular positioning. Its standard battery claim is up to six days and its official gallery and video are complete, but Molly&Cody does not disclose the cellular generation, radio bands, partner carriers, supported countries, minimum pet weight, or full subscription matrix. It therefore ranks only as a conditional option after buyers confirm local network support directly with the brand.
Pawfit
At 17.6 g, Pawfit Lite is the lightest true cellular GPS tracker in this cat ranking and is officially recommended from 2.7 kg. It adds 4G-LTE multi-network communication, five-second FIND updates, Bluetooth Find Nearby, IP68 protection, and a quick-release cat collar, but the published maximum battery life is only three days and a subscription remains mandatory.
Petcube
A low-cost 29 g LTE-M tracker with live location, Lost Dog mode, virtual fences, activity history, a light, and a buzzer. Its 30-day battery claim requires a Wi-Fi Power Save Zone, while remote tracking needs a paid plan and compatible LTE coverage that Petcube does not map publicly on the product page.
